Math problem: Who is correct, The Teacher or The Student?

[Reasonable Doubt]

Some simple math.

This too should be interesting.

 

[sandorski]

lol

 

[SsupernovaE]

I would have said 20.

 

[yhelothar]

The teacher didn't think about this one.
2 boards = 1 cut
3 boards = 2 cuts

 

[PlasmaBomb]

Yeah the teacher has done 10 minutes for 2 pieces = 5 min per piece...

Time required for 3 pieces = 3 x 5 = 15 mins.

There is a really obvious reason why this is wrong.

 

[HamburgerBoy]

I like the teacher's proof below her answer.

 

[DaTT]

Teacher is wrong.

 

[Doppel]

Lol

 

[pmv]

[JimmiG]

Teachers are always right, even when they're wrong.

 

[Raizinman]

What then is the correct answer? Show your proof.

 

[Newbian]

what then is the correct answer? Show your proof.

10 * 2 = 20.

I totally read the title as "Meth problem..."

Teachers are always right, even when they're wrong.

this. LOL. but there EXIST genuine/honest teachers who correct their mistakes.

 

[DrPizza]

Well duh, the new board is 12"x12". The first cut is 12" long. But the second cut is only 6" long.

 

[waggy]

this. LOL. but there EXIST genuine/honest teachers who correct their mistakes.

i have found them to be very rare. Hell I have heard of people getting in trouble for trying to get a question marked wrong corrected.

 

[MotF Bane]

Teacher fail.

 

[arcenite]

Teacher is wrong. Is this yours?

 

[arcenite]

What then is the correct answer? Show your proof.

Took 10 minutes to cut a a board into two. This means, 10 minutes for a single cut.

Then, if she has to make two more cuts to cut another board into 3 pieces, 2*10 = 20.

C'mon, I'm terrible at math and I picked this up.

 

[FallenHero]

Well duh, the new board is 12"x12". The first cut is 12" long. But the second cut is only 6" long.

Actually...that kinda makes sense. DAMN YOU DR. PIZZA!

 

[alphatarget1]

Kid is correct. It takes Marie 10 minutes to make one cut. Cutting a board in 3 pieces would require 2 cuts and thus 10 minutes. Marie is a n00b.

Sigh. How can the next generation be good at math when we have teachers who fails at simple reasoning? Teacher is a n00b.

You know you got a total fail when even the proof is wrong.

yeah so? i didn't see the OP say it was his kids homework.

 

[nanette1985]

I'm sure not hiring Marie to do any carpentry for me. At least I'm not paying her by the hour.
