Give the step-by-step reasoning process and then the final answer. There are 248 pages in a book. Joanna can read 16 pages per hour. On Monday, she reads for 3 hours. On Tuesday, she reads for 6.5 hours. How many more hours does she need to read to finish the book?
On Monday, Joanna reads 3 * 16 = 48 pages. On Tuesday, Joanna reads 6.5 * 16 = 104 pages. So far, she has read 48 + 104 = 152 pages. Thus, she has 248 - 152 = 96 pages left. She will need to read for 96 / 16 = 6 hours to finish the book.
The final answer: 6.
