A remote controlled toy car starts from rest and begins to accelerate in a straight line. The figure below represents "snapshots" of the car's position at equal 0.5 s time intervals. (Assume the positive direction is to the right. Indicate the direction with the sign of your answer.) t=1.0s at 0.4m

t=1.5s at 0.9m

What is the car's average velocity, in m/s, in the interval between t = 1.0 s to t = 1.5 s?
