A conveyor belt in a local M&M’s chocolate factory is 420 ft long. The yellow peanut M&M character hops on one end and runs in the same direction the belt is moving. When he gets to the other end, he turns and run back, against tje motion of the conveyor belt. The first trip takes 60 seconds and the return trip takes 210 seconds. How fast the peanut M&M character runs? How fast is the conveyor belt moving?
