Answer:3.71 m/s
Explanation:
Given
square track with sides 50 m
average speed is 5 m/s
Total running time=53.8 s
Total distance traveled in this time
i.e. Person has completed square track one time and another 69 m in second round
So displacement is 269-200=69 m
average velocity
Difference between average velocity and average speed is
5-1.28=3.71 m/s
