Jeff must do a book report. He reads 3 pages of his book in 13 minutes. He reads 9 pages of his book in 39 minutes. He reads 15
svlad2 [7]
Do you see a pattern in the given information?
 3 pages in 13 min
 9 pages in 39 min
15 pages in 65 min

the rate of pages per min is constant
3/13 = 9/39 = 15/65

the Question is asking for time.. So the we need the rate as min per page 13/3 so when multiplied by the number of pages it cancels to give minutes.

Units cancel out just like numbers do so you know that the problem is set up correctly.

(351 pages) * ( \frac{13min}{3pages})=1521 .minutes
