An interval is the spacing of time. For example: I ran for an interval of 10 minutes then walked for an interval of 30 minutes. Or each car has an interval of 0.5 seconds.
When Johnson broke the world record for the 200 meter dash at the Summer Olympics in Atlanta in 1996, he ran the first 100 meters in 10.12 seconds. As incredible as it may sound, he ran the second 100 meters in 9.19 seconds which, as of October 15, 2007, is .55 seconds below the world record in the 100 meter dash. Historians have compared that run with the long jump of Bob Beamon in the 1968 Summer Olympics in Mexico City where he broke the existing world record by 21 3/4 inches or .55 meters. He had a running start for the second 100.
9 x 2/60 = 0.3 mile, or 528 yards, or 482.8 metres
Look at the units! Minutes and miles per hour. Hours and minutes are both time but they are not the same.1hour = 60minutes. We have 20 minutes.20/60 = 1/3So we ran for 1/3 of an hour at 5mph.If we ran 2hours at 5 miles per hour (MPH), it's probably more obvious you ran for 10miles. That's 2 x 5. Which is Hours x MPH.So what about our calculation? Hours x MPH = 1/3 x 5 = 1.6667 miles.
140km per hour
100 feet in 10 seconds gives an average speed of 10 feet per second.
Im 13 and i ran it in 10.47 seconds
Speed is not measured in units of time (minutes, seconds). If you want the speed in metres per second, divide 1500 by 322.
A 48.8-second 440 (yards) equates to a time of 48.517seconds in the 400m
that's pretty fast
It is not possible to maintain the same speed over different distances.
distance/time ex. i ran 100 feet in 20 seconds. i ran 5 feet per second
Original Answer: 400 m/sThis answer is a speed, not a distance.You cannot determine what the distance traveled was since the speed is presumably decreasing for the entire manoeuvre. The best you could do is estimate the distance to be 400 metres. There is insufficient information to do otherwise.For example, if the plane touched down at a speed of 80m/s and didn't change speed until it ran into a wall 10 seconds later, it would have travelled 800m. Of course that would be "coming to a FINAL rest"... :-)
