Speed or rate r is a scalar quantity that measures the distance traveled d over the change in time Dt represented by the equation r dDt. The average speed of an object refers to the total distance it travels divided by the time which is elapsed. For example A car travels 3 hours.

Another formula acceleration a equals change in velocity Dv divided by change in time Dt calculates the rate of change in velocity over time.
