A building has two elevators that both go above and below ground.
At a certain time of day, the travel timer
it takes elevator A to reach height h in
meters is 0.89+16 seconds.
The travel time it takes elevator B to
reach heighth in meters is -0.8h+12
seconds.
what is the height of each elevator at this time? how long would it take each elevator to reach ground level at this time? if the 2 elevators travel toward each other, at what height do they pass eachother and how long would it take? if you are on an underground parking level 14 meters below ground, which elevator would reach you first?
