Question 20
This pedal-powered water pump is made from bicycle parts.
A 30-tooth gear on the pedals has a chain to a 15-tooth gear. On the same axle as the 15-tooth gear is a 32-tooth gear that drives a chain to a 40-tooth gear on the pump.
For every 100 complete revolutions of the pedals, how many times does the gear on the pump turn?
