Differences Between Instantaneous Speed and Average Speed?

Question

What is the Differences Between Instantaneous Speed and Average Speed? Or, Distinguish Between Instantaneous Speed and Average Speed.

Answer 1

Instantaneous Speed	Average Speed
1. Instantaneous speed is the distance travelled by a body per unit time at a particular point of the time (or infinitestimally small interval of time)	1. Average speed is the average distance travelled by a body per unit time over a certain measurable interval of time.
2. Instantaneous speed of a moving object can't be calculated by using the formula s / t because, here 't' should be immeasurably small tending to zero.	2. Average speed can be calculated from the measured values of distance and time.
