My bike reached a speed of 36 miles per hour. My bike tires have a radius of 14 inches. If I maintained this speed for 30 seconds, how many revolutions did my bike tire make?
--------------
Each revolution moves 2*14*pi inches.
1 mile = 5280 ft = 5280*12 inches.
1 hour = 3600 seconds

That's all you need to know.
