Miles is going to spend 1/6 of a day reading. He will read comic books, graphic novels, and novels. He reads 21 pages an hour when he reads novels, 30 pages an hour when he reads graphic novels, and 45 pages an hour when he reads comic books. If he reads each for 1/3 of his time, how many pages does he read? Let's think first. Chain of thought:
Miles will read for 4 hours because 24 x (1 / 6) = 4. He will read each type for 1 and 1 / 3 hours because 4 / 3 = 1 and 1 / 3. He will read 28 pages of novels because 21 x (1 and 1 / 3) = 28. He will read 40 pages of graphic novels because 30 x (1 and 1 / 3) = 40. He will read 60 pages of comic books because 45 x (1 and 1 / 3) = 60. He will read 128 pages in total because 28 + 40 + 60 = 128.
Therefore, the answer is 128.
