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
