An elevator travels down from the top floor of a skyscraper. Its height, in feet, is given
by the equation h = 1000 – 22t, where h represents the elevator's height, in feet,
and t represents the time, in seconds. What could the number 22 represent in the
equation?
a) the change in the elevators height for every one additional second.
b) how long it takes for the elevator to reach the ground floor
c) the elevators final height
d) the elevators height after one second
