Velocity is a vector quantity. It has both a magnitude and a direction. If we talk about instantaneous quantities e.g. how fast something is moving right now, at this instant, then its speed is just the magnitude of its velocity vector.
___________________________
On the other hand, if we talk about average quantities over some finite interval, things are different. A simple example. Suppose an object is moving in a circular path at a speed of 100 mph. That’s its average speed for one “revolution” (trip around the path) but its average velocity vector for one revolution is zero, because, when you add up (integrate) all the velocity vectors for that revolution, they cancel each other out.

Those definitions of speed and velocity are technical ones, used by physicists and engineers, for example. In everyday parlance, the same two words are often treated as synonyms, ignoring the vector aspects.

Explanation:
velocity of body can equal to speed if it is in linear motion but it can't exceed speed
hope it helps
