Question

Usha swims in a 90 m long pool. She covers 180 m in 1 minute by swimming from one end to the other and back along the same straight path. Find the average speed and average velosity of Usha.

Answer 1

Aloha There !!


Easy method :-


Displacement = 0

Average speed = $\frac{180}{60}$

                        =  3m / sec


Average velocity = $\frac{0}{60}$

                            = 0 Ans.
