Multiple Choice Answers
How long it takes for the elevator to reach the ground floor.
The elevator's final height.
The change in the elevator's height for every one additional second.
The elevator's height after one second.

Answer 1

In the equation \( h = 1250 - 25t \), the number 25 represents the rate at which the elevator is descending. Specifically, it indicates how much the height of the elevator decreases for each additional second of travel.

Therefore, the correct answer is:

The change in the elevator's height for every one additional second.
