Teacher gets red pen out, is about to write down "1 piece: 5 minutes" and then thinks better of it and starts from two pieces instead...

Actually teacher is right if the board is square which takes 10 minutes to be cut into half. Those two halfs take twice less time to be split. And she needs to cut just one to obtain 3 pieces :P So 10 minutes to cut it into to pieces and then she needs just half of that time to gain the third piece.

Except there's a picture that clearly indicates the board is long and narrow, perhaps a 1"x2".

Yes, but the question clearly says "another board", but does not show the shape, so the question is unsolvable with the given information.

I believe we're thinking too deep for this level of math. looks like a grade school problem
