Question

Example 8.3 Usha swims in a 90 m lon
pool. She covers 180 m in one minute
by swimming from one end to the other
and back along the same straight path
Find the average speed and average
velocity of Usha​

Answer 1

Answer:

average speed = 30 m/s and average velocity=0

Step-by-step explanation:

In this case displacement becomes 0 hence velocity is o zero.

avg speed= total distance/total time
