Question

A person riding the original Ferris Wheel is traveling at a speed of 0.495 mph. If one revolution takes 9 minutes, what is the diameter of the Ferris Wheel? Show your work.
1 rev is distance of pi D

so pi D feet/9 minutes = speed in feet/min

.495 mi/h * 5280 ft/mi * 1 h/60 min
= 43.56 feet/min

SO
pi D/9 = 43.56

D = 9 (43.56)/pi
or
D = 125 feet
