Answer

Brief Explanations:

A ramp is a simple machine. Work is force times distance. By increasing the distance over which the force is applied, the amount of force needed to lift the piano to the height of the truck (a fixed - height work) is decreased.

Answer:

It allows a smaller force to be applied over a longer distance.
