In kinematics, the speed of a moving object is the rate at which the distance travelled by the object changes with time. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity, which indicates additionally the direction of motion. Read more on Wikipedia
