riddles (open to anyone)

I also say 3 minutes

3 min for me also then

Well you might have the right answer, but using your formula above, after adding in the half a man, I don't see how you got there. Maybe you completely corrected your whole angle at it. You'll have to explain to get all the credit. (If your just letting other people guess still, that's cool too.)

Okay, here is how I came up with 3:

First you doubled the number of men, so that would double the output in the same amount of time, meaning 3 men could eat 3 pies in 1.5 minutes. But we want them to eat 6 pies. That is double the number of pies 3 men can eat in 1.5 minutes, so we need to double the time - now we have 3 minutes.

So 3 men can eat 6 pies in 3 minutes...

Super great job!

What happened to this thread?

Yeah, come on Dale, it's been a week...

Ok, so you are on a journey in a strange land, and you come to a y in the road. There is a sign that states "Between these two paths, you must choose. One of these paths leads to the town of truth, and the other to the town of lies. Choose wisely. If you find yourself in the town of lies, you will never escape. To help you make the right choice, there just happens to be a representative from each city stand right under this sign. You may ask these men a question, and they will answer, but be carefull, you may only ask one question and then both will answer." One man will always tell the truth, and the other man will always lie. What question will you ask?

It's something like: I would ask each dude which road to take. First I walk up to the liar ask him which road "he says the other dude would tell you to take the left road." He's a liar so I have to assume the truth teller would would say take the right-handed road. Then I walk up to the truth teller and ask him which road "he says the other guy would tell you the left-handed road is the road to take." Which he only speaks the truth about what the liar would say, which would be a lie.

End result: Take the opposite road of either answer.

I would simply ask each of them which road leads back to their home town. The liar would have to lie, and point to the town of truth. The truth teller would have to tell the truth, and point to the town of truth.

Very good!

Now imagine that you are in a room with two doors and two men. Same senario exept, one door leads to life, and the other to death. The men are still one liar and one truth teller (you don't know which one is which), but they are NOT FROM the two places, however they do know which is which. Then what would you ask?

Ask them which door the other guy would point to as the door to life. They will both point to the same door. Don't take that door, the other door will lead to life.

Or an alternate solution: Ask each of them which door the other would point to as the door to death. Both will point to the same door, and that is the door to life.

I think Bill has been using google!
