Answer 2

HEY DEAR YOUR ANSWER IS HERE
_______-_-_-_-Velocity is defined as the rate of travel of an object, along with its direction. Velocity tells you how fast an object is moving as well as in what direction it is moving. It is similar to speed, except that it also adds direction. So, while speed is directionless, velocity is directional speed..
Speed = Distance / Time
