Question

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

Answer 1

Length of the pool: 70m
Average speed:
Speed= Distance/Time
speed=140/60
speed=2.33 m/s

Velocity:
velocity=displacement/time

displacement=0( Since she comes back to the same place)

velocity=0
