Question

Vishnu swims in 70m long pool. He
covers 140m is one minute by swimming
from one
one end to the other and back
along the same straight path. Find
the average speed and average
velocity of Vishnu.​

Answer 1

total distance =140

displacement=0

total time=1min.=60sec.

average speed=total distance /total time

=180/60

=3m/s

======================================

average velocity=total displacement/

total time

=0/60

=0 m/sec

Answer 2

Answer:Given - s = 180m , t = 1min = 60 s

Solution - 1) Average speed = Total distance travelled / Total time taken

                                              = 180m / 60s

                                               = 3 m/s

                 2) Average velocity = Displacement  / Time

                         But as displacement =0m

                           Average velocity =0m/s
