###Human: 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?, ### Assistant: 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 answer is :  6
