Instantaneous speed is speed measured at a specific time. Speed is an average.
instantaneous speed.
Instantaneous speed:- It is the rate of change of position with respect to time,at that instant. Average speed:-Average speed is defined as the total path length travelled divided by the total time interval.
Average speed is the total distance divided by the total time. Instantaneous speed is the speed at one instant, that is found by taking the first derivative of the position, and evaluating it at t (time).
Only if speed is constant. There can be no acceleration if the average speed is equal to the instantaneous speed.

Instantaneous speed is the speed at a particular moment in time.The average speed of an object tells you the (average) rate at which it covers distance

Only if speed is constant. There can be no acceleration if the average speed is equal to the instantaneous speed.
Suppose you accelerate in your car from stopped to 50 km.hr-1. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km.hr-1. If your rate of acceleration was constant then your average speed was 25 km.hr-1.
It shows instantaneous speed.
Average speed and instantaneous speed are both measurements of the speed of an object. The instantaneous speed measures how fast the object is going at a particular moment, while average speed shows how fast the object was moving in total over time.
Instantaneous speed is the speed of a body at any one instant. There is really no such thing as the instantaneous speed, it is merely the average speed over a very short space of time.
The concept of average speed is somewhat simpler than "instantaneous speed".
