Question 1170260: A person is riding a Ferris wheel with a diameter of 80 feet. If a ride all the way around the circle takes 90 seconds, how fast is the rider traveling in miles per hour? Answer by VFBundy(438) (Show Source):
You can put this solution on YOUR website! Circumference of a circle = diameter * pi
Circumference of Ferris wheel = = 251.33 feet
Convert 251.33 feet to miles. There are 5280 feet in one mile. = 0.0476. The circumference of the Ferris wheel is 0.0476 miles.
Convert 90 seconds to hours. There are 3600 seconds in one hour. = 0.025. The Ferris wheel takes 0.025 hours to complete one circle.
Rate =
Rate = = 1.904 miles per hour
