Sean has to read a book during summer break. He read 144 pages in 3 hours on the way to his grandma's house. If Sean reads at the same pace, how long will it take Sean to finish his 264-page book?

Answer 1

Sean reads 144/3 = <<144/3=48>>48 pages per hour.
Thus, Sean will finish reading a 264-page book in 264/48 = <<264/48=5.5>>5.5 hours. Answer: \boxed{5.5}.
