Two classmates, Brennan and Isabella, plan to meet in the computer lab to type up their research papers. Brennan can type at a speed of 1 page per hour, whereas Isabella can type 3 pages per hour. So far, Brennan already has 7 pages typed up, compared to Isabella's 3 pages. Once they sit down and start typing together, the two students will reach the same page count before too long. What will the page count be? How long will that take?
