The tires on your bicycle have a radius of 13 inches. How many rotations does each tire make when you travel 1200 feet? Round your answer to the nearest whole number.

In one rotation, the linear distance covered  = 2 * pi * 13   = 26pi  inches

 

Converting 1200 ft to inches  = 1200 * 12 = 14400 in

 

So.....he number of rotations is :

 

14400 / [26 pi ]  ≈ 176  rotations
