Question

A runner is running around a square track with side 25m. He travels around the track twice, finally running back to the starting point. If the total time he takes to run around the track is 100s, determine average speed and average velocity.

Answer 1

Answer:

total distance traveled = 200m

total time taken = 100s

average speed = total distance/total time

= 200/100

= 2m/s

average velocity = displacement/total time taken

= 0/100

= 0m/s

Explanation:

Answer 2

Answer:

Average velocity is zero as displacement is zero.

Average speed is 2m/s as distance covered is 200m in 100s.
