Question

A boy swim in a 100m long pool. He covers 60 m with a velocity of 20 m/s and cover the rest of the distance with a velocity of 10m/s. Calculate the average velocity of the boy.

Answer 1

hi friend
here's your answer looking for

Distance in first part = 60 m
time = 60/20
=3sec

distance in second part = 100- 60= 40

time = 40/10
4sec

avg speed = total distance / total time

= 60+40/3+4
= 100/7
= 14.28m/s

hope it's helpful to you
