An elevator descends at a constant speed. What is the change in elevation after 19 seconds?

7 0

Answer:

he total time is 4 seconds. The elevator descends 10 feet each second so the total is:

4seconds x -10 feet/sec = -40 feet

The total change in elevation is -40 feet. You need the negative sign because the elevator is moving downward. Hope this helps!
