How fast do you read that though? I'm like the grand parent post, 50 pages is an onerous commitment, something I'll only get done if I'm really really into a book and have nothing else to do that day, or am stuck on a plane. It'll take me around eight hours of reading to finish a short young adult book, for example.

Not particularly fast. I'm probably average for the typical college-educated adult.

Obviously it varies with the density of the material.

You can work up to 50 pages. Start with 10 pages per night. After a week, add 10 pages. Repeat until you hit a number of pages you find worthwhile.
