Instantaneous and average speed

[alyafey22]

Can instantaneous and average speed be equal to each other in any why ? if it can can you please give me an example ??

Here's one situation in which they are equal. If the speed is constant, then the instantaneous and the average speed are the same. In other words, the speed at any instant is equal to the speed you calculate by taking the total distance traveled and dividing it by the time taken to travel that distance.

Be a more specific. Do you want to take average from the time when it was at rest to the instant at which you are taking instantaneous speed or average over a sufficiently long time. Also is it a theoretical case or purely practical?

 

[LostConjugate]

Instantaneous speed is just the average speed taken over a small time interval. If you take average speeds over different time intervals they may or many not be equal.
