Answer: instantaneous speed.


Speed describes an objects distance and the time it takes to get there.

Speed = [tex]\frac{Distance}{Time}[/tex]

Instantaneous speed describes an objects speed in that very moment.  Much like the radar guns that police use to calculate a person's speed on a road.

Velocity describes the speed and direction of an object.  

Ex. "That car is travelling 40 miles per hour North."
