7.5 mph

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.

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.

7.5 mph

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)
