On a day where I am reading a lot, I read an average of around 100 pages. If it's an easy book and I have no other duties that day, I may reach as much as 200 pages. On busier day I read anything from 50 to zero pages.
But on average, I am usually able to finish a book of around 700 pages in about a week or a bit more. Unless I am busier that average in that week, in which case it takes longer.
For example, I finished a bunch of Elric of Melniboné books recently, a total of about 1000 pages in 9 days. (But Moorcock is pretty easy to read. Many writers take more time than this.)
