this is not a trig question...
you don't need the 2 inches and 4 inches thing in your calculation. the reason they were there is to confuse you...
 
When the 4in wheel turns one revolution, how many revolutions does the 2in wheel turn? Can you figure out this relationship?
 
sorry... ignore what i just said... I misunderstood the question
 
hm.. still don't get it

I understand that for every 1 pedal, the 2in circle goes 2 revolutions. How do I figure out the speed from this?.. I'm stuck/confused..

Do you know the number of revolutions of the 14in wheel now?

What is distance is traveled per revolution of the 14in wheel?
