In lowest gear on a 10-speed bike, each turn of the pedals makes the wheels turn 3.4 times. In the highest gear, each turn of the pedals makes the wheels turn 1.8 times. With each turn of the wheels, the bike travels 6.5 feet. How much farther does the bike travel with each turn of the pedals in lowest gear than in highest gear?
distance covered in "low" gear = 3.4(6.5) = 22.1 ft
distance covered in "high" gear = 1.8(6.5) = 11.7
Find the difference in their distances.
