Question

stream in 90 metre long pool she covers 180 metre in 1 minute for swimming from one end to the other and back the same straight path find the average speed and average velocity of Usha. If you know the answer then only give otherwise no problem. Give the answer in detail​

Answer 1

average velocity is zero because there is not net displacement

net displacement is zero hence avg velocity is zero

avg speed, = total distance means length of path/total time to cover distance

so 180/60=30meter per second
