Question

Reena swims in a 100m long pool. She covers 200m in 1 minute going either way. The average velocity is

Answer 1

Here 100 m pool is the distance

She travels 200 m in 1 minute
Means she first go to the end of the pool then returns back.
So here displacement is 0
And Velocity is calculated on displacement/time

Hence here velocity = 0/1 = 0



Here velocity is 0m/s because there is no Displacement.



Hope you understand

Answer 2

hai here is your answer
200 --------->1 minute (60sec)
velocity =?(x)
distance = 200m
time = 60s
velocity = distance/time
v = 200/60
v=20/6
v=3.33333.....
this is your answer
