The term average velocity refers to a particular time interval. If this time interval is very long, the motion of the luge may change appreciably during the interval. A shorter time interval, and smaller displacement, will give us a value for the average velocity that more accurately represents the luge motion. In the limit of a very short time interval (actually, in the limit as this interval goes to zero), the ratio of displacement to time interval is called the instantaneous velocity, or simply velocity.
