An elevator travels down from the top floor of a skyscraper. Its height, in feet, is given
by the equation h = 500 - 25t, where h represents the elevator's height, in feet,
and t represents the time, in seconds. What could the number 500 represent in the
equation?

How long it takes for the elevator to reach the ground floor.

The height the elevator starts at.

The elevator's final height.
