a conveyor belt in the local m&ms chocolate factory is 420ft long. the yellow peanut m&m character hops on one end and r
uns in the same direction the belt is moving. when he gets to the other end he turns and runs back, against the motion of the conveyor belt. the first trip takes 60 seconds and the return trip takes 210 seconds. how fast does the peanut m&m character run? how fast is the conveyor belt moving?
