Question

nisha swims in a 90m long pool. she covers 180m in 1 minute by swimming from one end and back along the same straight path. find the average speed and velocity of nisha

Answer 1

here,total distance covered by Nisha(s)=180m
time taken(t)=60 sec
average speed =s/t
=180/60
=3m/s
now, displacement of Nisha = 0m
time taken=60sec
average velocity=total displacement/total time
=0/60
=0m/s
