Question

What it the correct equation for average velocity?
a. average velocity = speed / time
b. average velocity = time / displacement
c. average velocity = displacement / time
d. average velocity = time * displacement

Answer 1

The correct answer is C. 

Velocity = displacement/ time

Or V = D/T for short! :)

Answer 2

The magnitude of velocity is  (displacement) / (time) .

Velocity also needs a direction.  The direction of velocity
is the direction of displacement ... the direction from the
start-point to the end-point.
