Question

usha swims in a 90m pool. she covers 180m in one minute by swiming from one to the outher end to the outher and back along the same straight path. find the average speed and average velocity of usha

Answer 1

Average speed = Total Distance/Total Time = 180m / 60 sec = 3 m /s
Avarage velocity = Total Displacement/ Total Time = 0 / 60 sec = 0
Total displacement = 0 as the starting point and the end point is the same.
