Passenger elevators in tall buildings can automatically be controlled up to about 22miles per hour, with automatic deceleration at stops, etc. These are passenger elevators. Far higher velocities ( up to maybe 40 or 50 miles per hour) may be had in mining personnel cage elevators for mine workers at deep levels - for example in South Africa. These are working appliances and not luxury devices- so the ride can be much rougher than say Rockefeller Center. potential for accidents increases with velocity as should be obvious.
from what I hear, they still use elevators. Know of a guy who repairs conveyor systems and has had to go down elevators (sometimes it takes an hour) to get underground! This is in 2009!
Becasue they ELEVATE you to different stories in a building! i hope that helps. :P
Yes they did.
The company named for the inventor, Elisha Otis, the Otis Elevator Company.
Elevators help your takeoff by raising the tail of the aircraft and putting the whole aircraft in 'flight' attitude.

i think about 8 elevators go up to the top
40 mp/h
The rising and descending speed gos up to 18 m/s (59 ft/s).
it took one min. to get up to the 103thrd floor, and your ears pop on the way up and down is what i experienced.
The Willis Tower is in Downtown Chicago and is 1,450 feet tall. The elevators can reach a top speed of just over 18 miles per hour.

Elevators are the control surfaces on the rear wing that make the aircraft go up or down. -There are no figures as they are all different.

elevators are related to math because elevators have numbers on them
maybe what they are looking for is in the place where there are elevators :) or maybe they must face their fears in order to conquer them and truly prove their worth in the post-apocalyptic world to come. just a theory.
