A person jogs eight complete laps around a 400m track in a total time of 14.5 min. What is the average velocity?

Velocity is equal to the displacement travelled per unit time. In this problem, we are given with a 400 m track and a time of 14.5 min. Hence the velocity of the person jogging is 400 m per 14.5 minute or 27.59 meters per minute. Converting to seconds, the answer is 0.46 meters per second
