# Give Reasons for the Following:If the reading on the odometer of a vehicle in the beginning of a trip and after 40 minutes were 1048 km and 1096 km respectively, will the reading on the speedometer show this velocity where the vehicle is moving? Support your answer with reason.

Odometer is used to measure the distance travelled by the vehicle.

Given:

Initial Reading = 1048 km at t = 0 seconds

Final Reading = 1096 km at t = 40 minutes = hr

Average Speed = = = = 72 kmhr-1

Calculations using the readings of odometer gives the average speed.

Whereas, the speedometer gives the reading of instantaneous speed.

Thus, the two values, that is one calculated and one on the speedometer may not be the same.

Both can only be same if the vehicle has been moving with constant velocity throughout the measurement.
