You run
completely around a 400m track in
80s. What was your average velocity?

The average velocity of the runner for the given displacement and time of motion  is 5 m/s.

The given parameters:

The average velocity of the runner is determined by dividing the total displacement by the time of motion as shown below;

Thus, the average velocity of the runner for the given displacement and time of motion  is 5 m/s.

V=?

S=400m

t=80s

V=S/t

V=400/80

V=5m/sec

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example
