Yup, math checks out. 80k words a book, so say 120k words/week. If you read 200 wpm then this would take about 10 hours or 1.5h per day.
Just try to avoid the styles of “quantity oriented” reading practice taught in e.g. law school. Nothing is more guaranteed to make books unappealing as a pleasure activity. People with learning disabilities and reading-oriented jobs may have different experiences with those techniques, though.
