Speed - Wikipedia, the free encyclopedia
Speed is the rate of motion, or equivalently the rate of change of distance. Speed is a scalar quantity with dimensions length/time; the equivalent vector quantity to speed is velocity. Speed is meas...

Average speed is a rate. In kinematics, a rate is always a quantity divided by the time taken to get that quantity (the elapsed time). Since average speed is the rate position changes, average speed = distance traveled/time taken.

Velocity - Wikipedia, the free encyclopedia
In physics, velocity is the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per ...
