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 pages of his book and 65 minutes. his book is 351 pages long, how many minutes will it take him to read the entire book? create a ratio table and explain how you found your answer.

Do you see a pattern in the given information?
 3 pages in 13 min
 9 pages in 39 min
15 pages in 65 min
