Is it possible for the instantaneous speed to be greater than the average speed? Explain.

The mean value theorem tells us the average velocity must be between the minimum velocity and the maximum velocity. The only way it can be either the minimum or the maximum is if velocity is constant. So of course instantaneous velocity can be greater and can be less.

Explanation:

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
