I need help with the question below.

Question

Joe runs 9.25 times around a track in 1,125.803 seconds. If one lap around the track is 502.3 meters, which is the best estimate of the runner's average speed in meters per second (m/s)?

Answer 1

9.25 · 502.3m = 4646.275m

4646.275m / 1125.803 sec ≈ 4.12707641m/sec

 

This is approximately 12 feet per second. Rather fast!
