one at the rear wheel.? a bicycle has two sets of gears, one at the pedals and one at the rear wheel. A typical 10-speed bicycle has two gears on the chain wheel and five gears on the rear wheel. the peed at which the bicycle travels depends on three independent factors.
* the first is the speed at which the cyclist pedals to turn the front gear (measured in rotations per minute).
* the second is the gear ratio from the front gear to the rear wheel ( a ratio between the number of teeth on the front gear compared to the number of teeth on the front gear compared to the number of teeth on the rear gear).
* the third is the size of the rear wheel (measured as the diameter of the wheel ).
A) develop a formula that predicts the velocity in km/h for a bicyclist.
B) how fast will a cyclist travel in km/h who is pedaling at 50 rpm with a 42 toothed gear on the front, a 14 toothed gear on the back and a tire with a diameter 26 inches?
C) in what ways can a cyclist pedal more slowly but maintain the same speed?
