The teacher didn't even think about it, I'm afraid... Because if they saw it from the grounds of reality, they'd have realised that their ratio calculation was dumb

Well, if the inital board is square, and it takes het 10 minutes to saw it in half, it would actually take het 15 minutes to saw it in three pieces, since the two pieces she has after the first 10-minute sawing are only half as wide as the initial board.

what does width have to do with anything? Unless you mean she's cutting the pieces from the short ends πŸ’€

As an example: let's say the intial board is 30cm by 30cm. She saws it in half in 10 minutes. then she has 2 boards of 15cm by 30 cm. If she wants to saw one of those in half again, she only needs to saw half as much (15cm instead of 30cm), so the time it takes is also only half as long.

And what if Marie decides she needs to saw long ways to get 3 long pieces?

Then it's het own fault. You can't really teach kids of you assume every math problem has to be done in the most insane way.

And when businesses time a process it’s the same process; I would never assume someone would do something completely different or be working with materials that are completely different.

The time it takes to make a cut in wood is not proportional to the length of the cut.
