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.
The Attempt at a Solution
I feel like that should be a really simple question if I had formula. We were given that:
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.
