Speed can be defined as the distance traveled divided by the total time taken. So, speed = distance/time.
While velocity can be defined as the displacement divided by the total time taken. So, velocity = displacement/time

Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. Contrast this to a slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time. An object with no movement at all has a zero speed.

Velocity is a vector quantity that refers to "the rate at which an object changes its position." Imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. While this might result in a frenzy of activity, it would result in a zero velocity. Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity. If a person in motion wishes to ...more

Speed is a scalar quantity while velocity is a vector which mean speed has no specific direction where as velocity is governed by a direction

Speed is scalar
Velocity is vector
