About how many pages of fiction novel reading do you think high school teachers should assign for homework per night?

He says it is a fiction novel, so it can't be that horrible. If I was a teacher I would take 3 hours, which is the time a good student should be spending each night on homework, divide it by 6, (number of classes which assign homework), which is 30 minutes, and then read for 30 minutes, trying to absorb, and see how many pages HE gets through. Then subtract 10, because his students will be slower, and that is the number of pages he should assign.
