Question

what are average speed and instantaneous speed

Answer 1

Instantaneous speed is the exact speed that a body is moving at, at a given instant in time. It is a true measure of the body's motion for that point in time. An average speed tells you how much distance a body covers during a certain time span, but it does not tell you much about the actual motion that occurred.

Answer 2

average speed = total distance tarvelled / total time taken
