2.5 fps

circumference = 2 X pi X r = 3.14 X 3 = 9.42 ft

1 sec - 2.5 ft

50 sec - 125 ft

9.42 ft approx 9.5 ft is 1 rev

125 ft - how many revolutions

125/9.5 = 13.4

Completed 13 revolutions and in the 14th revolution.

C - 13

Feet in 50 seconds - 2.5*50 = 125
Circumference = 3*pi

Revolutions = 125/(3*pi) ~ 13
