This problem has to do with speeds & sprockets. If anyone can come up
with an easy solution to this problem, it would be greatly


Here is the problem:

The front sprocket of a 3-speed bike is 6” in diameter. The
diameters of the back sprockets for the 1st, 2nd, and 3rd speeds are
4”, 3”, and 2” respectively. The diameter of the back wheel is 25”.
For each speed, calculate how many times the back wheel will turn and
how far the bike will move when the pedals move around once.
Solutions should include diagrams and explanations.
