Answer:
Velocity is the speed with displacement .
( Rate of displacement ).
Explanation:
Displacement is a vector quantity, which is the distance traveled in a definite direction.
Speed is the rate of distance traveled and is the ratio of distance to time.
Velocity is the rate of displacement and is given as the ratio of the displacement to the time.
For example if a car is traveling at a speed of 50 kmph, specifying the direction of travel gives its velocity, like 50 kmph towards east or right. Speed is a scalar where as velocity is a vector quantity.
