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?
Step-by-step reasoning process below:
6
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.

.

So, the final answer is 6
