SOLUTION: EVERY TIME THE PEDALS GO THROUGH A 360 DEGREE ROTATION ON A BICYCLE, THE TIRES ROTATE 3 TIMES. IF THE TIRES ARE 24 INCHES IN DIAMETER, CALCULATE THE MINIMUM NUMBER OF COMPLETE ROTA

Question 363086: EVERY TIME THE PEDALS GO THROUGH A 360 DEGREE ROTATION ON A BICYCLE, THE TIRES ROTATE 3 TIMES. IF THE TIRES ARE 24 INCHES IN DIAMETER, CALCULATE THE MINIMUM NUMBER OF COMPLETE ROTATIONS OF THE PEDALS NEEDED FOR THE BICYCLE TO TRAVEL AT LEAST 1 MILE.

The tires dia = 2 ft
The circumference = 2 pi feet
5280/(2pi) =~ 840.34 revs of the tire
--> 841 revs to go 1 mile of the tire
The pedals make 841/3 = 280.33
--> 281 pedal revs per mile
