Two classmates, Troy and Mason, plan to meet in the computer lab to type up their research papers. Troy can type at a speed of 2 pages per hour, whereas Mason can type 1 page per hour. So far, Troy already has 5 pages typed up, compared to Mason's 10 pages. Once they sit down and start typing together, the two students will reach the same page count before too long.
