Dustin and Sam are both reading. Dustin can read 75 pages in an hour. Sam can read 24 pages in an hour. How many more pages does Dustin read in 40 minutes compared to Sam? Let's think first. Chain of thought:
Dustin reads 1.25 pages a minute because 75 / 60 = 1.25. Dustin reads 50 pages in 40 minutes because 40 x 1.25 = 50. Sam reads .4 pages a minute because 24 / 60 = .4. Sam reads 16 pages in 40 minutes because 40 x .4 = 16. Dustin reads 34 more pages than Sam because 50 - 16 = 34.
Therefore, the answer is 34.
