The Mercy College office started with one old copy machine. After a while, they bought a new
copy machine. The new copy machine can xerox one box of student files in 1 hour. The old
machine can xerox the same amount of paper in 3 hours.
How long will it take to xerox one box of student papers if Mercy College office runs both copy
machines at the same time?
How can you be sure that your answer is right?
