A Ferris wheel completes 4 revolutions in 10 minutes. The radius of the Ferris wheel is 40 feet.
What is the linear velocity of the Ferris wheel in inches per second?
Enter your answer, rounded to the nearest tenth, in the box.
1 revolution is 1 circumference
C = 2·pi·radius = 2·pi·40 ft = 80·pi ft = 253.3274123 ft
= 253.3274123 ft x 12 in / ft = 3015.928947 in
10 min = 10 min x 60 sec / min = 600 sec
4 revolutions / 10 min = 4 x 3015.928947 in / 600 sec = 5.0 in/sec
