Question

rain swims in an 80 in long pool.he covers 160m in one minute by swimming from one end to the other and back,along the same straight path. find his average speed​

Answer 1

Explanation:

Distance = 180 m

Time = 1 min = 60sec

Average speed = total distance covered / total time taken

= 180m / 60 sec

= 3m/s

Displacement = 0m/s ( as usha come back along the same path so, the intial and final position is same )

Average velocity = displacement/ time

= 0m / 60 s

= 0m/s
