It takes me less than 30 seconds to read the page. Let's be generous and make it 60 seconds. So in an hour you can read 60 pages. 300 pages book in five hours. Two books will take 10 hours. So reading for one hour each week day and 2.5 on weekend will take you through two books a week.
There are books however which you just cannot put down and go through them in one or two sittings.
