45 is the answer. I think OP thinks 40 would be the obvious answer.

Nvmd. I see the 45. Darn. Oh well thanks for brain exercise.

No. Kids need to learn (and maybe be explicitly told) that a key to do well on tests like this is figuring out what the teacher wants. Clearly here you are not supposed to split it down the middle. The trick here is that it does not take 2x to do 10 cuts v 5, but 2x + 1.


But it's not 10 cuts, Einstein. It's 9 cuts for 10 pieces.


Sorry. Cuts should be pieces.

2x plus 1 cut. Sorry. Did not realize I had to be so specific with adults. 45 minutes.

Right. Not 2x. Which would be 40. It is 2x plus 1, which would be 45.

40.

Takes him 2x as long for 2x the amount.

OP here. This was my first thought, and my kid's. But everyone who said 45 minutes is in fact correct. 5 minutes per chop and 9 chops to get 10 pieces.

You might want to factor in how tired Mr. Sawyer gets. The rate of work slows down as production increases.
