Velocity measures the motion of an object that starts passing from one place and starts heading towards another place. Once we put it another way, you employ measures of velocity to make a decision how quickly you or any object in motion will reach a destination from a given location.

Measures of velocity provide you to make timetables for travel and plan your schedule accordingly. For eg., if a train leaves ABC Station in Bangalore at 6 p.m. and you allow the speed at which the train is moving the opposite station, you'll predict when it'll reach the destination station.
