Answer:
His average speed is 5.33 m/s.
Explanation:
Average speed is the ratio of total distance traveled to the total time taken.
Average speed = Total distance / Total time
The person covers the track of 400 meters 4 times. So, the total distance traveled by him is 4 * 400 = 1600.
5 minutes = 5 * 60 s = 300 s
= ( 4 * 400) / (5 * 60)
= 1600 / 300
= 5.33 m/s
