A person jogs eight complete laps around a 400 - m track in a total time of 14.0 min. Calculate the average velocity, in m/s.

The track has a circumference of 400 m. This is the distance traveled per lap.

Because the person made 8 laps, the total distance traveled is

8 * 400 = 3200 m

The time taken for the 8 laps is 14.0 min = 14*60 = 840 s.

The average velocity

= distance/time

= (3200 m) / (840 s)

= 3.8095 m/s

Answer: 3.8 m/s (nearest tenth)
