1. The problem statement, all variables and given/known data In a bicycle, the ratio between the size of the wheel sprocket to the size of the crank sprocket is 2.5 which means... An example of one of the answer choices is: The rear wheel turns ___ times for every full rotation of the pedals. 2. Relevant equations 3. The attempt at a solution I feel like that should be a really simple question if I had formula. We were given that: ωwheel=(R1/R2)ωpedal R1 is the radius of the crank sprocket R2 is the radius of the wheel sprocket This would mean that ωwheel=(2/5)ωpedal, but that doesn't really help.
