Question 92535
the elevator in the washington monument takes 75 seconds to travel 500 feet to the top of the floor. what is the speed of the elevator in miles per hour?
-------------
(500 feet/75 seconds)( 1 mile/5280 feet)(3600 seconds/1 hour) 

= (500*3600)/(75*5280)(miles/hour)

= (1800000/396000) (miles/hour)

= 4.5454... mph
