If I were you I would find how many cups nathan can scoop in a minute because not only its the easiest way it's the fastest so what you can do to find that is divide 8.5 by 2 which is 4.25.
since you know how many he can scoop in a minute you can do 8 times 4.25 because their is 8 minutes and 8 times 4.25 is 34
