The instantaneous velocity of an object is always equal to its average velocity
The answer is: if its speed is constant
When objects move, instantaneous velocity is the speed at which the object is moving at the same instant. This speed is usually calculated when using temporal measurements of the body's movement. If a body moves a specific distance in a specific period of time, its average speed will be the distance it travels divided by the time required to travel it. Since speed is a test of a combination of force and time, instantaneous speed gives us a good idea of how speed changes over time. In short, the instantaneous speed of an object is always equal to its average speed, which can be useful when calculating the motion of the object under certain conditions.
