Reason : Average velocity is equal to total distance divided by total time taken.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

The speedometer of an automobile measures the instantaneous speed of the automobile.
Average velocity $= \frac{N e t d i s pl a ce m e n t}{T im e t ak e n}$
