Expert Solution

Step 1

Introduction:-

Average speed-

We know that the Average speed of the object is defined as the ratio of the total distance covered by the object to the time taken to travel a distance and the average speed is a scalar quantity that has magnitude only.

$average speed = \frac{Total distance}{time taken}$

The average speed is the rate at which the total distance of an object is covered.

Instantaneous speed:-

The instantaneous speed is defined as the speed of the object at an instant of time. or the ratio of the distance traveled by the object at a particular time interval is known as instantaneous speed.
