Thanks. You just reminded me to put "able to solve this" on my auto-hide list along with all of the other retarded template thread phrases.

Maybe it was a square board, and the first cut split it vertically in half, and the second cut one of those halves horizontally in half.
The first cut would then take twice as long as the second.

Same logic applies with slightly different wording.

10min/2pieces = 5 min per piece

3 pieces * 5 min/piece = 15 min

>> No.9366946

>>9366942
Then the 10 minutes was how long it took her to find a man to do the job.

So the answer is probably only a couple of minutes, since the man will ready be there for the second board.

10 divided by 2=5, 5 x 3=15, ergo, it's 15.
This is 1st grade stuff, literally.

>> No.9367723

a-am I retarded guys? It only takes 1 cut to cut it into two pieces, and one cut takes 10 minutes. Similarly, it takes one cut of one of the two pieces to create a further three pieces. So it takes two cuts in total, at 10 minutes per cut, that's 20 minutes.

You are correct. Cutting through the 4x4 takes her ten minutes. Cutting through it twice takes 20 minutes.

>> No.9367754

>>9366720

If it took her 10 minutes to saw it once, it should take 20minutes to saw it twice...

>> No.9367844

>>9366720
The correct answer is 20

10 minutes to cut into 2 pieces implies she only saw the board once. Literally break a pencil in half once and see how many pieces you have.

[===] + [======] -->

Two arrows = two steps to get to three pieces. Each hack/saw/cut is 10 minutes, so it takes Marie 20 minutes total to produce 3 boards, because she only needs to cut the board twice.

No because since it takes here 10 minutes to cut a board into 2 pieces it takes her 5 minutes to cut a board into 1 piece. After that it's literally 2nd grade multiplication.

For those who are taking math above calculus, are the problems as arbitrary and vague as this? Or are the alternate possibilities explicitly negated

Sawing a board in two pieces only requires one cut. Sawing it in three pieces requires two cuts. 20 minutes. idiots

Wait, if it takes her one cut to cut it into 2 pieces (10 min), it will take her another 10 min to cut the other piece a.k.a 20 min. Not sure how to explain it, somewhat like the pawn in chess.

if she can cut them however she wants, then the answer isn't 15 either, assuming marie's cutting time is inversly proportional to the area of the cutting plane intersection with the board, it's a very small number close to 0, because marie will just knock 2 atoms off of the corner.

>> No.9369008

>>9369004
Yeah, because "knocking off atoms" is just a simple thing you can do in a time close to 0. She wants to saw a board into pieces, not knock off atoms, and "knocking off atoms" would probably be much harder and take much longer than just using a saw

>> No.9369015

How can you cut a board into 1 piece exactly? At which points do I apply pressure so as to break a pencil into a single piece?

10 Minutes for 3 pieces. Saws are usually pretty flexible, so Marie bends it in such a way that she can saw the board into exactly 3 pieces.
