Question

Q7.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:

average speed of john = total distance covered / total time taken

                                  => 160 / 60 = 2.67 m/s

average velocity = total displacement / total time

 displacement means distance between initial and final positions

here the final and initial positions are same so displacement = 0

so average velocity = 0
