3 km in 5 min => his average speed is 36 km in 60 min, that is 36 km per hour. Clearly an extremely fast runner and way faster than MY average speed.
If someone runs 10 miles in 90 minutes their average speed is 6.67 mph
4.6ms
The equation would be 2x+2(x+2)=28 when x= the speed of the slower runner. If you solve for x you get 6, which is the speed of the slower runner. Then if you add 2 you get the speed of the faster runner-8
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!
The average speed of a runner who runs 500.0 m in 1.3 min is 6.41 m/s.
15km/hour

15 kph
10/40=.25
He is running at an average speed of 21.31 mph.
1 and 5/6m per seconds
if a runner has gone 10km in 40 min. then what you do is divied 40 in to 10 and it come out to be 4 so then you get your answer ...10km/40min.=4km pm( pure a minute)
10mph average
2.8 m/s A+ program answer (:
