Question

A person jogs eight complete laps around a 400-m track in a total time of 14.5 min. Calculate the average speed and the average velocity in m/s

Answer 1

d = 400 m (8 laps) = 2400 m

t = 14.5 min

v = 0

average t = 14.5 min (60 sec per min) = 870 s/8 laps = 108.75 s per lap

speed = distance /time

400/108.75 sec = 3.67 m/s
