The elevator need to climb 117 feet and it reaches 117 feet in 6.5 seconds only. Now, let’s solve for the unit rate of the elevator. What is it’s speed.
=> 117 feet is the distance that the elevator needs to climb.
=> 6.5 seconds is the now.
To find the speed let’s follow that formula. S = d/t
=> 117 feet / 6.5 seconds
=> 18 feet per seconds
Unit rate of the elevator speed = 18 feet/s
