A tire of a moving bicycle has radius 16 in.
If the tire is making 2 rotations per second, find the bicycle's speed in miles per hour.
:
2 * circumference * 3600 sec divided by inches in a foot and feet in a mile

Put this in your calc:
%28%282%2A2%2Api%2A16%2A3600%29%29%2F%28%2812%2A5280%29%29 = 11.434 mph
