Problema Solution
Ron’s Recycle Shop was started when Ron bought a used paper-shredding
machine. Business was good, so Ron bought a new shredding machine. The
old machine could shred a truckload of paper in 4 hours. The new machine
could shred the same truckload in only 2 hours. How long will it take to shred a truckload of paper if Ron runs both shredders at the same time?
