Question

Q. John swims in a 80 m long pool. He covers 160 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 John

Answer 1

answer

Speed is 2.7 m/s and velocity is 0

Explanation:

John swims and covers 160 m in one minute.

Which means, distance covered by John is 160 m and time taken to complete is 1 minute.

1 minute = 60 m

Hence,

⇒ Speed = distance / time

⇒ speed = 160 m / 60 s

⇒ speed = 2.7 m/s

As John returns to the same place, displacement( distance from initial point to final point ) is 0, therefore, velocity = displacement / time = 0 / 60 s = 0
