4Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

5 A car starts from rest and acquires a velocity of 54 kmh1 in 2 minutes. Find the acceleration and distance travelled by the car during this time. Assume acceleration of the car is uniform. Ans: 0.125 ms2, 900 m.
