What is the average speed of a runner if he ran 40 km in 4 minutes?

That is a very fast runner, not even a cheetah could to that...
40 000 / (4 * 60) = 166.7 meters per second (more like the speed of a jet fighter!)
Now if it were 4 hours for the 40 km then a well trained horse might survive the run (2.8 m/s) that's still almost three times the speed that Ussain Bolt runs the 100!

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.
What is average speed if you ran 5 kms in 36 minutes?
If you ran 5 kms in 36 minutes, then your average speed is exactly 5 km per 36 minutes. Scaling it to a more familiar unit, it's also equal to 81/3 km per hour, and about 5.178 miles per hour.
How many minutes did it take if you ran 7 miles?
depends on what your rate/speed is... for instance, if you walk at an average pace (i.e. 3mph) it would take you 140 minutes (2 hours and 20 minutes). If you ran at an average pace of 5.5 mph, it would take you 76.4 minutes (roughly 1hr 16 minutes)
