When is the average velocity of an object equal to the instantaneous velocity?
a) always
b)never
c) only when velocity is constant
d)only when velocity is increasing at a constant rate

c) would be the answer since you could cross out a). I do know that instantaneous velocity is the speed at that small instant in time. Is c)correct?
