How do you work out the average speed if you ran a 7 minute mile?

Just write down exactly what you've included in the question, and eventually
something will look promising:
--> 7 minutes per mile
--> 1 mile per 7 minutes = (1 mile) / (7 minutes) = (1/7) (mile/minute)
1/7th mile per minute is a perfectly good number for speed. But if it doesn't seem to
mean much, you can convert it to miles per hour.
1 hour is 60 minutes. So, whatever ground you can cover in one minute, you can cover
60 times as much in an hour.
(1/7) (mile/minute) x (60 minutes/hour) = (60/7) (mile/hour) = 8.57 mph

Kerry ran a 10-mile race She ran the first three miles in 21 minutes She ran the last seven miles in 63 minutes What was her average speed in the race?
Simply add your times and divide by the distance (or visa-versa).21 minutes + 63 minutes = 84 minutes84 minutes/10 miles = 8.4 minute miles.Note, this is a convenient form to calculate speed for runners. However, the "standard" would be in MPH (or the metric equivalent).(10 miles / 84 minutes)*(60 minutes/hour) = 7.14 MPHA common fallacy might be to calculate the speed in each leg of the race and average.3 miles in 21 minutes = 7 minute miles.7 miles in 63 minutes = 9 minute miles.If you average these two you get 8 minute miles WHICH IS INCORRECT.The problem with this is that the runner ran each pace for different distances. If the distances at each pace were the same, then this would work.
How long does it take to travel 300 miles by car?
It depends on your average speed. If the roads permit an average speed of 60mph, it would take you 5 hours. To work it out (using T=D/S): Time (hours) = 300 miles divided by average speed (mph)
How would you find the average speed if the person went 3 different speeds in a length of 5 hours?
You need to work out how far they travelled at each speed (distance = speed x time) then add all three distances together to get a total and divide by 5 hours to get the average speed
How do you calculate how fast a object travels?
An example: A football travels at A speed unknown. Measure A distance for travel. Throw the ball and time it with A stopwatch. Take the feet and devide by seconds. 100feet, for 8seconds = 12.5 feet/per second. multiply 12.5 (feet) by 60 (seconds in A minute) =750 feet/per minute multiply 750 (feet) by 60 (minutes in an hour) = 45,000 feet/per hour. Divide 45,000 (feet) by 5,280 (feet in A mile) = 8.522 Miles/per hour This will work for any measuring scale, You just need to know all the different measurement steps. I.E. - feet in A mile, seconds in A minute, minutes in an hour. ECT.
If The fastest person runs 2964 feet in 22.4 seconds how many miles per hour is that show the work?
5280 ft = 1 mile 1 hr = 3600 seconds speed = distance ÷ time = 2964 ft ÷ 22.4 s ≈ 132.32 ft/s = 132.32 × 3600 ft/h ≈ 476,357 ft/hr = 476,357 ÷ 5280 mph ≈ 90 mph They are a very fast runner. The world record for 800m (approx 2624 ft) is 100.91s which is an average speed of approx 17.7 mph. The world record for 100m (approx 328 ft) is 9.58s which is an average speed of approx 23.4 mph. As distances increase, the average speed will drop as humans cannot sustain the fast pace.
How do you work out the speed of land speed record?
The current ultimate land speed record was set in 1997 at 763 mph which is recorded at top speed through a 1 mile speed trap. The run is then ran in the other direction within 1 hour. The average of both runs is the official record.

How many miles from Birmingham to Chichester?

What would 4 minute 53 second time convert to in a 1 mile track race?
If you are wondering how that time equates to average I have bad news if you are 13 Y.O. or more. You have a lot of work to do, the average reasonably fit teenager can do that with no training. [or they could in the fifties when I was in school and Roger Bannister was our hero].
How do you work out driving time?
Divide the distance by the average speed.
Does 30 scenes work for a thirty minute tv show?
it doesent there are only about 14 scenes in your average 30 minute tv show
What is the formula for converting milliseconds to feet per minute?
There is no formula for this - the units don't work. On one side you have time (milliseconds) but on the other you have speed=distance/time (feet/minute).
How long does it take to drive 48 miles going 80 mile per hour?
At 80mph, it takes 45secs to travel one mile (three-quarters of a minute). Therefore it will take three-quarters of 48mins to travel the specified 48 miles. 48x 0.75 = 36mins, unless there is a policeman with a speed gun in the way!
How can you calculate average speed from a distance -time graph?
Speed is distance divided by time so pick the section you want to work out the average for, work out how much distance has been traveled in that section and divide it by how much time has passed for that section.
What is the average time for a woman 59 years old to run a mile?
A good mile time can range anywhere from under 6:00 till about 11:00 minutes. It depends on your shape. Actual time is not really all that important unless you are trying to run a marathon. Just start by walking and work up to mixed walking/running and eventually all running. Start slow and work on speed and endurance.
My Speed and trip meter not working 1995 200sx?
There should be a wire that connects to the top of your transmission, if it isn't connected then speed and trip meters don't work. It takes like a minute to do it by hand.
How long does it take to travel 300 miles by car?
It depends on your average speed. If the roads permit an average speed of 60mph, it would take you 5 hours. To work it out (using T=D/S): Time (hours) = 300 miles divided by average speed (mph)
