Going 65mph for 30 seconds how far would you get? None of these formulas work without distance. How would I find the distance from time and speed?

if i travel 0.01 inches per second and I need to travel 999999999 kilometers, it takes 556722071 Days and 20:24:34 WHAT

4. How long does it take to do 100m at 3kph ? No I thought you would just divide 100 ÷ 3 = which 33.33333 so 33 seconds or so I thought. But apparently it 2 mins.

This was the best tool ive ever used that was on point from speed to distance and time Calculator

This was somewhat unhelpful as I know the time and distance, but not the speed. Would be helpful if this calculator also could solve the other two as well.

If a total distance of 2 miles is driven, with the first mile being driven at a speed of 15mph, and the second mile driven at a speed of 45 mph: What is the average speed of the full 2 mile trip?

hi sorry im newly introduced to this and i dont understand how to use it but in need to find the distance if i was travelling in the average speed of 15km/hr in 4 hours how far would i travel

D= 697 km T= 8 hours and 12 minutes S= ?

if a train is going 130 miles in 50 minutes, how fast is it going in miles per hour ??

whats the speed if you travel 2000 miles in 20hours?

How long would it take me to drive to Mars at 100 miles per hour and how much gas would I use in a 2000 Ford Mustang000000/ Also, how much CO2 would I release into the air?

great tool helped me alot

A car can go from rest to 45 km/hr in 5 seconds. What is its acceleration?

Guys how much time will a cyclist take to cover 132 METRES With a speed of 8 km/ph

@Mike Depends on how fast that actually is. For every 10 mph above 60, but below 120, you save 5 seconds a mile. But between the 30-60 area, every ten saves 10 seconds a mile (if I am remembering correctly), and every 10 between 15-30 is 20 seconds. Realistically, it isn't likely isn't worth it, unless it is a relatively straight drive with no stops, in which case you will likely go up a gear for the drive and thus improve gas efficiency for the trip. Only really saves time if it is over long trips 300+ miles (in which case, assuming you were on the interstate) that 5 seconds a mile would save you 25 minutes from the drive, making it go from 4h35m to 4h10m. For me, I have family across the U.S., so family visits are usually 900-1400 miles. Even only driving 5 above usually saves me 90-150 minutes or so (since I often have stretches where I drive on US highways which have 55 mph speed limits)

I would like to know if driving fast is worth it for short trips. If I drive 10 MPH over the speed limit for 10 miles, how much time do i save ? Is there an equation for that ?

it helps me in lot of stuff

awesome, helped me notice how long my taiga (electric seedoo) is going to last.

Very good! This helped me a lot.

Speed, Distance & Time Calculator

Use this speed calculator to easily calculate the average speed, distance travelled and the trip duration of a vehicle: car, bus, train, bike, motorcycle, plane etc. Works with miles, feet, kilometers, meters, etc..

• How to calculate the average speed of a car?

    Speed, Distance & Time Calculation

In order to use the above speed, distance & time calculator, or do such math on your own, you will need to know two out of three metrics: speed, distance, time. You will need to convert the metrics to the same time and distance units, e.g. miles, kilometers, meters, yards, feet, and hours, minutes or seconds. For example, if you have speed in mph (miles per hour), time should also be in hours. If you have distance in kilometers, then speed should also be in km/h (kilometers per hour).

The unit of the result will depend on the units you input, but our speed calculator will conveniently display additional units where appropriate.

    Average Speed formula

The formula for average speed, also called average velocity in physics and engineering, is:

where v is the velocity, d is the distance, and t is the time, so you can read it as Speed = Distance / Time . As noted above, make sure you convert the units appropriately first, or use our speed calculator which does that automatically. The resulting unit will depend on the units for both time and distance, so if your input was in miles and hours, the speed will be in mph. If it was in meters and seconds, it will be in m/s (meters per second).

Example: If you took a plane from New York to Los Angeles and the flight was 5 hours of air time, what was the speed of the plane, given that the flight path was 2450 miles? The answer is 2450 / 5 = 490 mph (miles per hour) average speed. If you want the result in km/h, you can convert from miles to km to get 788.58 km/h.

    Distance formula

The formula for distance, if you know time (duration) and the average speed, is:

Example: If a truck travelled at an average speed of 80 km per hour for 4 hours, how many miles did it cover in that time? To find the miles covered, first, calculate 80 * 4 = 320 km, then convert km to miles by dividing by 1.6093 or by using our km to miles converter to get the answer: 198.84 miles.

    Duration (Time) formula

The time, or more precisely, the duration of the trip, can be calculated knowing the distance and the average speed using the formula:

where d is the distance travelled, v is the speed (velocity) and t is the time, so you can read it as Time = Distance / Speed . Make sure you convert the units so both their distance and time components match, or use our trip duration calculator above which will handle conversions automatically. For example, if you have distance in miles and speed in km/h, you will need to convert speed to mph or distance to kilometers. The time unit of the result will match the time unit of the speed measure, so if it is measured in something per hour, the result will be in hours. If it is measured in some unit per second, the result will be in seconds.

Example: If a train can travel 500 miles with an average speed of 50 miles per hour, how long it would take it to complete a 500-mile route? To find the answer, use the formula and substitute the values, resulting in 500 / 50 = 10 hours.

    How to calculate the average speed of a car?

Say you travelled a certain distance with a car or another vehicle and you want to calculate what its average speed was. The easiest way to do that would be by using the calculator above, but if you prefer, you can also do the math yourself. Either way, you need to know the distance to a satisfactory approximation, for which you can use a map (e.g. Google Maps) to measure the distance from point to point. Make sure you measure closely to the path you took, and not via a straight line, unless you travelled by air in which case that would be a good approximation. Of course, having a GPS reading of the distance would be more precise. Then you need to know the travel time. Make sure you subtract any rests or stops you made from the total trip duration.

If the total distance travelled was 500 miles and the time it took you was 5 hours, then your average speed was 500 / 5 = 100 miles per hour (mph). If the distance was 300 kilometers and it took you 5 hours to cover it, your speed was 300 / 5 = 60 km/h (kilometers per hour).

How Long Does It Take To Run 4 km? (Explained in Detail)

4 kilometers or 2.48 miles is a distance that is not specific to any sort of race.

However, you will often find it in the training plans of beginners and experienced runners alike.

In this article, you will find out how long it takes to run 4 km and you will find answers to the most common questions on this topic.

On average, it takes approximately 23 minutes to run 4 km, which means that the average running pace is 9:15 minutes per mile. Numerous factors, such as age, sex, fitness level, experience, weather, and terrain will all affect the result.

When calculating the average time it takes to run 4 km, I used  the statistics on the average time for 5 kilometers .

Depending on the running pace, the table shows how long it takes to run 4 km.

You can use my running pace calculator to calculate the time it takes to run 4 km at a certain pace. You can also calculate how fast you will run if you run 4 km in a certain amount of time.

What is the average 4 km time for beginners?

For beginners, the average 4 km time is about 27 minutes, which means that the average running pace is 10:52 minutes per mile (6:45 minutes per kilometer).

If you are a beginner, you might not be able to run the whole 4 km continuously without stopping. In that case, combine running and walking segments.

For example, your training session can consist of 6 alternations between 2 minutes of running and 2 minutes of walking.

Gradually reduce your walking segments and increase your run time. You must listen to your body and be patient. In time, your fitness level will only get better and better.

Tip If you are a beginner, walk breaks are a useful training method that will help you build your fitness. Over time, you will build enough endurance and you will no longer need walk breaks.

Read more: Is It Bad To Take Walk Breaks During A Run?

What is the average 4 km time for intermediate runners?

For intermediate runners, the average 4 km time is about 16 minutes, which means that the average running pace is 6:26 minutes per mile (4:00 minutes per kilometer).

Intermediate runners usually run 4 km as part of a warm-up routine or as part of a cool-down.

What is a good average 4 km time?

Most runners think that a good 4 km time is everything under 19 minutes, which means that the average running pace is 7:39 minutes per mile (4:45 minutes per kilometer).

Good 4 km time depends on numerous factors, such as age, sex, fitness level, experience, time, and terrain on which you run.

It is difficult to give a precise answer because it varies from person to person.

For someone, a good 4 km time will be 16 minutes, while another runner will be unhappy with that result. A good 4 km time is the result you will be happy with.

Tip Don’t compare yourself to others. Everyone is different. Follow your results and push your boundaries. Enjoy running and progress gradually to train without injury, because that’s most important.

Is it enough to run 4 km a day?

Running 4 km a day is enough if you want to improve your overall health, be in good shape, and lose weight.

If you want to improve your running results, you need to combine different types of workouts and run different distances.

Will running 4 km a day get me in shape?

Running 4 km a day will get you in shape, especially if you do strength training twice a week in addition to running, and if you pay attention to what you eat.

However, do not forget about adequate recovery.

Therefore, no matter how good you feel, take at least one day of complete rest every week.

Is it good to run 4 km every day?

If you run 4 km every day, you will improve your health, strengthen your muscles, burn more calories, and generally feel better.

However, if you want to improve your running skills, it is not good to run 4 km every day.

You must have complete rest at least one day a week to reduce the risk of injury and the occurrence of overtraining.

Likewise, if you want to progress, you have to put your body under different kinds of strain by doing different workouts.

How hard is it to run 4 km?

Beginners can find it difficult and challenging to run 4 km continuously, without stopping.

On the other hand, experienced runners will not find 4 km challenging.

However, if they run at a fast pace and push their boundaries, they will also find 4 km difficult and challenging.

Is it possible to run 4 km without training?

If you are active and in good shape, it is possible to run 4 km without training.

If you have not done any sports so far, and you spend most of your time sitting, be careful. In the beginning, combine walking and running.

I always advise a smart and consistent approach to training regardless of someone’s current level of fitness.

How to run 4 km without stopping?

To run 4 km continuously, without stopping, follow this advice:

• Initially, combine running and walking segments
• Gradually shorten your walking segments and run longer
• Train at least 3 times a week
• Take at least 1 day off between workouts
• Don’t think about pace, listen to your body
• Run at a conversational pace at which you can say a full sentence while running without exhausting yourself

How many calories do you burn by running 4 km?

Running 4 km will burn you an average of about 250 calories.

The exact number of calories spent while running 4 km depends on the weight and fitness of the runners, their pace, the terrain they run on, and the weather conditions.

The heavier you are, the more calories you will burn because you have to carry more weight and work harder to run the same distance at the same pace.

Example According to the calories burned running calculator , a runner who weighs 175 lbs will spend approximately 327 calories by running 4 km at a pace of 9:39 min/mi, while a 130 lbs runner will spend approximately 243 calories.

Did New Jersey just have an earthquake? Yes, in Hunterdon County. Aftershocks continue.

If you felt that, you're not alone.

A 4.8-magnitude earthquake shook up the region shortly before 10:30 a.m. Friday, followed by two aftershocks of magnitude 2 at 11:20 a.m. and magnitude 2.2 at 1:32 p.m.

Stay tuned for updated coverage .

Where was the earthquake?

The epicenter of the earthquake was in Whitehouse Station, Hunterdon County, at 10:23 a.m.

The earthquake was 4.77 kilometers north northeast of White House Station and the depth was five kilometers. People felt the rumble from Maine to Norfolk, Virginia, officials said.

Will there be aftershocks?

Two aftershocks of magnitude 2 and magnitude 2.2 have struck since the quake, according to the United States Geological Survey. There is a small chance of an aftershock of 4.8-magnitude or greater, said Paul Earle of the United States Geological Survey.

This quake was felt by millions, Earle said, adding that East Coast quakes travel five times farther than West Coast quakes, because the rock here is harder.

When was the last earthquake in New Jersey?

The last earthquake in the Garden State was on March 15, measuring magnitude 2.2 struck near Whitehouse Station in Hunterdon County about 3 p.m., according to the U.S. Geological Survey.

The earthquake occurred at a depth of 8.7 kilometers, the survey said.

Prior to March 15, the last earthquake in New Jersey was a 1.7-magnitude that occurred near the Lake Telemark section of Roxbury Township in Morris County in August 2022, according to the survey.

There have also been earthquakes at the Jersey Shore: a 2.2-magnitude at Tuckerton in June 2021; a 3.1-magnitude near Marlboro in September 2020; and a 1.4-magnitude that occurred near Keansburg in August 2017.

What was the strongest earthquake at Jersey Shore?

One of the strongest earthquakes at the Jersey Shore was a magnitude 3.8 quake that struck near Freehold on January 30, 1979.

“Objects were shaken from shelves and minor cracks were reported in masonry walls in a few towns near the epicenter” during that quake, according to the Northeast States Emergency Consortium.

Earthquakes of less than a magnitude 3 are considered weak quakes with little noticeable shaking, according to the California Earthquake Authority.

South River homes shake, branches knock, alarms triggered

In South River, the start of rumbling was accompanied by small knick-knacks and toys falling from shelves. 

While at first it seemed likely that a truck or construction vehicle was headed down the street, it soon became apparent that something else was at play.

The house continued to shake for 20 to 30 seconds, as the rumbling noises continued, branches knocked against the walls, roof and windows, clanging noises were heard from a metal chimney pipe and a glass break security alarm was triggered. 

The power remained on, and there was no apparent damage at an electrical substation on Southside Avenue nor at a neighborhood park on the street.

Loud rumbling, shaking in Milltown 

In Milltown, about 30 miles from the earthquake’s epicenter, a loud rumbling noise accompanied shaking on Herbert Avenue in Milltown. A songbook fell off a piano inside one house.

Neighbors ran out of their homes and stood on lawns and porches asking each other what had just happened.

“It felt like my house was going to fall down,” said one resident. Another wondered if a residential construction project might have collapsed and caused the rumbling.

No visible damage was apparent on the block.

4.8 magnitude earthquake rattles NYC, New Jersey: Live updates

NEW YORK – A 4.8 magnitude earthquake recorded in New Jersey that shook residents in surrounding states and New York City on Friday morning was one of the strongest in state history.

The temblor was reported about 5 miles north of Whitehouse Station, New Jersey, at about 10:23 a.m. Friday, according to the United States Geological Survey. The epicenter was about 45 miles from New York City, where residents reported shaking furniture and floors.

“Earthquakes in this region are uncommon but not unexpected. It’s likely people near the epicenter are going to feel aftershocks for this earthquake in the magnitude 2-3 range, and there’s a small chance there can be an earthquake as large or larger, following an earthquake like this,” Paul Earle, a seismologist at the USGS Earthquake Hazards Program told reporters. “In terms of our operations, this is a routine earthquake … Immediately we knew this would be of high interest and important to people who don’t feel earthquakes a lot.”

People reported feeling the shaking as far north as Maine and as far south as Norfolk, Virginia, following the quake, according to USGS. Scientists said those in the affected area should listen to local emergency officials and be prepared to seek cover if aftershocks occur.

“If you feel shaking, drop, cover and hold,” Earle said.

No major disruptions or damage have been reported in New Jersey or New York.

"We have activated our State Emergency Operations Center. Please do not call 911 unless you have an actual emergency," said New Jersey Gov. Phil Murphy.

President Joe Biden spoke with Murphy about the earthquake and the White House is monitoring the situation.

“He thinks everything's under control,” Biden told reporters before leaving the White House for a trip to Baltimore. “He’s not too concerned about it, the governor of New Jersey, so things are all right.”

New York Gov. Kathy Hochul said the quake was felt throughout New York, and officials are assessing impacts and any potential damage.

In Yonkers, New York, Mayor Mike Spano said City Hall shook but no injuries were reported.

"A few moments ago our entire house shook for about 25 seconds or so here in Mendham, New Jersey," former New Jersey Gov. Chris Christie said.

USGS is still investigating the exact fault line at the center of Friday’s quake and said it occurred in a region with dozens of fault lines that were more active millions of years ago.

4.0 magnitude aftershock strikes hours after earthquake

Officials in New York and New Jersey alerted residents to an aftershock Friday evening, nearly eight hours after the earthquake.

A 4.0 magnitude aftershock slammed New Jersey at around 6 p.m., with an epicenter about four miles southwest of Gladstone, according to the USGS. New York City’s emergency notification system alerted residents to the aftershock minutes later, urging people to remain indoors and call 911 if injured.

Hochul said there were no reports of serious damage after the aftershock, and officials were continuing to assess critical infrastructure.

The aftershock Friday evening was at least the third that USGS recorded after the quake struck.

As of Friday afternoon, the USGS aftershock forecast predicted a 36% chance of aftershocks at a 3.0 magnitude or higher, an 8% chance of aftershocks at a 4.0 magnitude or higher, and a 1% chance for aftershocks at a magnitude of 5.0 or higher over the next week.

USGS scientists said informal observations can be a big help in understanding earthquakes, especially in a region where they’re less common.

“We encourage people to fill out the ‘Did You Feel It?’ reports on our website,” said Sara McBride, a scientist with the USGS Earthquake Hazards Program. “This citizen science project is critical in terms of building our knowledge around earthquakes.”

By midafternoon on Friday, the agency said it had received more than 161,000 reports, and extrapolated that the quake had been felt by millions of people. McBride acknowledged that earthquakes can be nerve-wracking for people who don’t live in seismologically active regions, and said knowledge is power in combatting that discomfort.

“The best thing you can do to relieve any unsettling feelings you might have is to learn how to protect yourself during shaking and how to prepare for earthquakes in the future,” she said.

Man getting vasectomy during earthquake recounts experience

One Horsham, Pennsylvania, man shared his unusual earthquake experience, saying the tremors hit when he was in the middle of receiving a vasectomy.

"The surgeon sort of froze and all of us kind of seemed a bit confused," Justin Allen told USA TODAY . "Even when the surgeon said 'that’s gotta be an earthquake,' I thought he was joking."

Luckily, Allen's doctor was able to resume the procedure after a brief pause, and the rest went off without a hitch. Now recovering at home, Allen said it's an experience no one involved will forget, especially because his social media post about the incident has since gone viral.

"My wife says that 'this is a clear and obvious sign that we should not have any more kids,'" Allen said.

New Jersey resident thought sound from earthquake was an explosion

Madeline Nafus had just finished feeding her 7-week-old baby when, simultaneously, she was thrown off balance and the loudest sound she’d ever heard rang out.

“I thought it was either an explosion or a bombing because of how loud it was,” said Nafus, who lives in Long Valley, New Jersey, a few miles from the earthquake's epicenter. “It was just terrifying.”

Nafus, 29, watched as her light fixtures swung and wine glasses, framed photos and a 6-foot elk head crashed onto the floor. Feeling as if her “house was going to crumble,” she picked up her baby boy, grabbed some blankets and headed outside. Meanwhile, her friend came running downstairs and picked up Nafus’ quivering dog, Olivia, a small golden doodle.

After about 15 seconds, the rumbling went away and only occasional, minor tremors could be felt. Nafus called her husband, who was teaching a golf lesson at the time, and then their 2-year-old’s day care.

“They said the children were all confused and asking a lot of questions but that they were OK,” she said.'

How common are East Coast quakes?

Earthquakes are less frequent in the eastern part of the country than in the west, but they have occurred in every state east of the Mississippi River, according to the USGS.

"Since colonial times people in the New York – Philadelphia – Wilmington urban corridor have felt small earthquakes and suffered damage from infrequent larger ones," according to the USGS. "Moderately damaging earthquakes strike somewhere in the urban corridor roughly twice a century, and smaller earthquakes are felt roughly every two to three years."

USGS officials also said that even smaller-magnitude quakes are more likely to be felt more widely on the East Coast than similar size quakes on the West Coast due to the rock properties of eastern soil, which can cause concern to East Coasters not used to the tremors.

Rocks in the eastern part of the country are much older than in the west, by up to millions of years. Those older rocks have been exposed to more extreme temperatures and pressure, and faults have had more time to heal. Seismic waves travel across the resulting harder and denser faults much more efficiently, so the effects of a quake are felt across a larger area. In the West, faults are newer and absorb more of the seismic wave energy without spreading as far.

Quake felt in Massachusetts

In Auburn, Massachusetts, more than 200 miles from the earthquake's epicenter, Jerry Steinhelper was on a video call for work when his house began to tremble. His dog Maize started barking, and books and trinkets fell from their shelves. He looked out the window and saw trees shaking.

“I thought at first it may be ice falling off the roof. But it kept going and the entire house was shaking,” he told USA TODAY. “Then I just knew it was an earthquake.”

Steinhelper, 55, lived in San Diego in the 1980s and experienced temblors there, but he’s never felt one in Massachusetts, where he’s been for over 25 years.

“It was an interesting 10 to 15 seconds,” he said.

'It felt like a plane crashed outside' near epicenter

Nicole Kravitz, 33, was baking muffins at the cafe she co-owns with her husband in New Jersey when the floor began to shake. She and the cooks looked at each other for a few moments, and then at some stacked plates and glasses that had started vibrating.

Their eatery, Branchburg's Best, is located in New Jersey's Somerset County, near the epicenter of Friday’s earthquake.

“It felt like a plane crashed outside,” she said. “No one knew what was happening.”

Some workers ran out the door to see if something had smashed into the building while she checked the basement for damage. Meanwhile, Patrick Tucker, her husband, who was picking up beef from a nearby farm, watched agitated chickens and cows run around in their pens, visibly shaken by the quake.

Kravitz said the intensity of the earthquake made her feel like she was back in Southern California, where she had lived for several years before she returned to her home state in 2016.

Quake was one of the strongest to ever impact New Jersey

Friday's earthquake was the most significant in New Jersey since 1884 , when an Aug. 10 earthquake somewhere near Jamaica Bay, New York, toppled chimneys and moved houses off their foundations as far as Rahway, New Jersey, 30 miles away.

Other than that quake, there were only  three earthquakes in modern history  that caused damage in the state: 1737 (New York City), 1783 (west of New York City) and 1927 (New Jersey coast near Asbury), according to New Jersey Office of Emergency Management records.

The Dec. 19, 1737 earthquake is believed by modern experts to have been a 5.2 magnitude quake. Charted as taking place in the greater New York City area, some accounts say its epicenter was near Weehawken. State records show it threw down chimneys. Chimneys were also hurled down during the Nov. 29, 1783 quake. Estimated at a 5.3 magnitude that originated in modern-day Rockaway Township, according to state records, it was felt from Pennsylvania to New England.

The Aug. 10, 1884 quake, estimated at a 5.2 magnitude was the last the state has seen of its significance and was felt from Virginia to Maine, according to state records.

New Jersey business owner describes worst quake ever felt but went right back to work

It was a busy day for La Bella Salon & Spa in Lebanon, New Jersey, when an earthquake struck near the rural township.

About a dozen stylists and customers, some whom were getting their hair dyed while others got manicures and eyelash extensions, all froze as the building rattled for about 30 seconds.

“People started to feel the shaking, and it got worse and worse. We were like ‘Oh, my god, what is going on?’" said shop owner Rosanne Drechsel. “I thought a truck hit the building or something.”

After the tremor subsided, nearly everyone in the building started receiving texts and phone calls from friends and family, Drechsel, 61, said.

Nothing was damaged and no one was injured, but Drechsel, who was born and raised in New Jersey, said it was “by far the worst earthquake” she had ever felt.

“We all went back to work and finished the appointments,” she said. “Customers are calling now to see if we're still open and if they can still make their appointments later on today.”

'It was scary': Quake rattles shelves in Brooklyn bodega

In Brooklyn, residents said they felt their buildings shake and many went outdoors after the rumbling stopped to check in with neighbors.

Julio Melo, a deli worker, said he thought the sounds of the earthquake resembled those of a large truck going down the street. But when Melo, 32, looked around and saw beer bottles rattling on store shelves, and a potted plant shimmy down the counter, he thought it might be something bigger, he told USA TODAY.

“I looked at my employee and he had the same tragic face on as me, it was scary,” he said at Jenesis’ Grocery Corp. in Brooklyn’s Bedford-Stuyvesant neighborhood.

Where was the earthquake felt?

Residents and officials said the earthquake was felt throughout New York, as well as in New Jersey, Connecticut, Pennsylvania and elsewhere. It was also felt as far away as Cambridge, Massachusetts, about 250 miles away from the reported epicenter.

Charita Walcott, a 38-year-old resident in the Bronx borough of New York, said the quake felt "like a violent rumble that lasted about 30 seconds or so."

"It was kind of like being in a drum circle, that vibration," she said.

Earthquakes common in the region, but the size is unusual: Expert

Chuck Ver Straeten, a geologist and curator of sedimentary rocks at the New York State Museum, told USA TODAY it’s not surprising this earthquake happened where it did.

“New York, around New York City going into New Jersey, there’s a lot of earthquakes historically down there. Happens every year,” he said. But it’s less common for them to be of such a high magnitude. It’s not surprising that many people felt it, he said. Usually, earthquakes in the region are at a lower magnitude and less likely to be felt.

Ver Straeten said the real question now is if this is just a precursor to a larger quake.

“You never know what is the earthquake, what is a pre-earthquake, what is an earthquake happening after the main earthquake, you just have to see,” he said. “One slip along the rock fault, when one happens, it makes other areas around there more tense also and they start to slip and you slip again and slip again.”

But, he added, it would be unlikely for a larger quake to follow this one. In the Northeast, it’s more common for one large quake to be followed by smaller aftershocks, rather than a mounting series of tremors. 

What does magnitude mean in an earthquake?

Magnitude is a measurement of the strength of an earthquake . Officially it's called the Moment Magnitude Scale . It's a logarithmic scale , meaning each number is ten times as strong as the one before it. So a 5.2 earthquake is moderate while a 6.2 is strong.

The magnitude and effect of an earthquake, according to Michigan Technological University :

◾ Below 2.5: Generally not felt

◾ 2.5 to 5.4: Minor or no damage

◾ 5.5 to 6.0: Slight damage to buildings

◾ 6.1 to 6.9: Serious damage

◾ 8.0 or greater: Massive damage, can totally destroy communities

Intensity scales, measured in Roman numerals, are used to describe how strong the earthquake felt to people in the area.

According to the California Earthquake Authority , an intensity of I is typically felt only under especially favorable conditions. A IV, which leads to light shaking, is felt indoors by many, but not typically outdoors. It might awaken some people at night and lead to a sensation like a truck striking a building. A parked car would rock. Intensities VI and above would be strong, frightening and felt by all, with the damage increasing up to a X where the shaking would be violent. Some well-built wooden structures would be destroyed and most masonry and frame structures along with their foundations would be ruined.

While you might have heard the term " the Richter Scale " used to describe earthquakes, it is no longer commonly used because it was only valid for certain earthquake frequencies and distance ranges.

Speed of Light Calculator

Table of contents

With this speed of light calculator, we aim to help you calculate the distance light can travel in a fixed time . As the speed of light is the fastest speed in the universe, it would be fascinating to know just how far it can travel in a short amount of time.

We have written this article to help you understand what the speed of light is , how fast the speed of light is , and how to calculate the speed of light . We will also demonstrate some examples to help you understand the computation of the speed of light.

What is the speed of light? How fast is the speed of light?

The speed of light is scientifically proven to be the universe's maximum speed. This means no matter how hard you try, you can never exceed this speed in this universe. Hence, there are also some theories on getting into another universe by breaking this limit. You can understand this more using our speed calculator and distance calculator .

So, how fast is the speed of light? The speed of light is 299,792,458 m/s in a vacuum. The speed of light in mph is 670,616,629 mph . With this speed, one can go around the globe more than 400,000 times in a minute!

One thing to note is that the speed of light slows down when it goes through different mediums. Light travels faster in air than in water, for instance. This phenomenon causes the refraction of light.

Now, let's look at how to calculate the speed of light.

How to calculate the speed of light?

As the speed of light is constant, calculating the speed of light usually falls on calculating the distance that light can travel in a certain time period. Hence, let's have a look at the following example:

• Source: Light
• Speed of light: 299,792,458 m/s
• Time traveled: 100 seconds

You can perform the calculation in three steps:

Determine the speed of light.

As mentioned, the speed of light is the fastest speed in the universe, and it is always a constant in a vacuum. Hence, the speed of light is 299,792,458 m/s .

Determine the time that the light has traveled.

The next step is to know how much time the light has traveled. Unlike looking at the speed of a sports car or a train, the speed of light is extremely fast, so the time interval that we look at is usually measured in seconds instead of minutes and hours. You can use our time lapse calculator to help you with this calculation.

For this example, the time that the light has traveled is 100 seconds .

Calculate the distance that the light has traveled.

The final step is to calculate the total distance that the light has traveled within the time . You can calculate this answer using the speed of light formula:

distance = speed of light × time

Thus, the distance that the light can travel in 100 seconds is 299,792,458 m/s × 100 seconds = 29,979,245,800 m

What is the speed of light in mph when it is in a vacuum?

The speed of light in a vacuum is 670,616,629 mph . This is equivalent to 299,792,458 m/s or 1,079,252,849 km/h. This is the fastest speed in the universe.

Is the speed of light always constant?

Yes , the speed of light is always constant for a given medium. The speed of light changes when going through different mediums. For example, light travels slower in water than in air.

How can I calculate the speed of light?

You can calculate the speed of light in three steps:

Determine the distance the light has traveled.

Apply the speed of light formula :

speed of light = distance / time

How far can the speed of light travel in 1 minute?

Light can travel 17,987,547,480 m in 1 minute . This means that light can travel around the earth more than 448 times in a minute.

Speed of light

The speed of light in the medium. In a vacuum, the speed of light is 299,792,458 m/s.
