Question 1092528
 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
