Question

A person goes along a straight road of length 50m and covers 100m by moving from one end to the other end and come back along the same road find the average speed and average velocity if person takes 20 minute

Answer 1

Answer:

Average speed - Total distance/Total time

Total distance=100m

Total time= 20 min= 1200 seconds

Avg speed = 100/1200 = 1/12m/s

Average velocity = Total displacement/Total time

Total displacement = 0m

Therefore avg velocity = 0/1200= 0m/s
