If emma pedals for 150 revolutions of the chain wheel, how far will she travel? Round to the nearest foot. can anyone please explain to me how this problem is done

This isn't hard if you take it step by step. You just have to know the steps.
• First, you figure out how many times the rear wheel turns for each turn of the pedal (cause it's attached to the chain wheel, and goes around with it).
• Then you figure how far each turn of the rear wheel carries the bike -- that's gonna be equal to its circumference. F
