for every revoluyion of front wheel the rear whell makes 20/30 revolution
for 240 revolutions of front wheel it will make 240* 20/30
=160
You can put this solution on YOUR website! if the 30 front wheel revolves 240 times the 20 back wheel must go the same distance and revolve more times since it is smaller.
30*240=7200 distance
7200/20=360 revolution for the 20 back wheel
