Answer 2

Answer:

The speed of the bus is measured by the speedometer is the Instantaneous speed of the bus. Hence, the correct option is (2) Instantaneous speed of the bus.

Explanation:

A speedometer is a device that is used to measure instantaneous speed. As the reading in the speedometer is 40 km/h, it must be the instantaneous speed.

Instantaneous speed can be defined as the speed at a particular instant of time.

Average speed can be defined as the total distance traveled by the object in a particular time interval.

Velocity is the change in displacement with respect to time in a particular direction.

Average velocity can be defined as the total displacement traveled by the object in a particular time interval.

Hence, the speedometer measures the speed at any particular instant in time. The reading in the speedometer is 40 km/h is the instantaneous speed.
