The number of pages someone can read in 4 hours depends on several factors, including reading speed and complexity of the text. On average, a person can read about 50-60 pages per hour, so it's reasonable to estimate being able to read around 200-240 pages in 4 hours. However, individual reading speed and the nature of the material can cause significant variation.
4 pages.
John read 80 pages out of 240 pages last week, which is 80/240 or 1/3 of the book. This week, he read 60 pages out of 240 pages, which is 60/240 or 1/4 of the book. Therefore, he has read a total of 1/3 + 1/4 = 7/12 of the book. To find out what fraction he still has to read, subtract 7/12 from 1 (the whole book), which equals 5/12. So, John still has 5/12 of the book left to read.
