It takes you 13.5 minutes to run 8 full laps around a 400m track. Find your average speed and average velocity for the run, both in m/s.

Answer 1

Average speed= total distance /time taken= = 3200/13.5•60 =3.95 m/s
Average velocity = total displacement/time taken = 0.

Answer 2

p''p

Answer 3

0, velocity around a lap is always zero because velocity is displacement over time. Displacement in this case is 0, therefore 0/time = 0
