Brain teaser / puzzle corner (part 1)

A brain teaser and a chance to earn some free minerals. The first person to post the correct answer will win 1000 minerals from me. Here we go:

Four people went hiking together and they got lost. The sun has set, they are now in total darkness, and they came across a hang bridge that they decided that they would need to cross.

The hange bridge is in poor shape with missing sections, and it can only support two people at a time. They only have one flashlight, so they would need to cross two at a time, and have one person return with the flashlight to the other side so others may cross.

The four are all capable of crossing the bridge at different rates individually. The fastest guy can cross the bridge in one minute, the second guy can do it in two minutes, the third guy can do it in five, and the slowest guy can do it in ten minutes. But since they have to share one flashlight per two man team, they would always have to match the speed of the slowest person at each crossing. For instance, even though the 1 minute guy can cross in only a minute when he's by himself, if he was to cross with the 10 minute guy, he would have to slow down to cross in 10 minutes because they are sharing one flashlight.

You need to get all of them across the hang bridge in 17 minutes.

Example:

1-min guy & 2-min guy cross = 2 minutes
1-min guy returns with flashlight = +1 minute = 3 minutes
1-min guy & 5-min guy cross = +5 min = 8 min
1-min guy returns w/ flashlight = +1 min = 9 min
1-min guy & 10-min guy cross = +10 min
TOTAL = 19 minutes

You can change the crossing order any way you like, but be sure to do it in 17 minutes.

To any guests reading this, if you know the answer, quickly register and post it up. As a welcome gift, I will reward an extra 1000 minerals on top of the 1000 to any new members with the correct answer. This is your chance to register and start with 1000 minerals right off the bat.

Ah heck, if the reply with the correct answer posted reads a post count of 20 or less when I see it, I'll give a bonus 500 minerals to that too. Good luck.

 

Re: Brain teaser / riddle / quiz...

I will take a crack at this! :thumbup:

BAH!

EDIT -

A. 1 Minute Man
B. 2 Minute Man
C. 5 Minute Man
D. 10 Minute Man

A + B = 2 Minutes
B = +2 = 4 Minutes
C + D = +10 = 14 Minutes
A = +1 = 15 Minutes
A + B = +2 = 17 Minutes

 

Re: Brain teaser / riddle / quiz...

1-min guy & 2-min guy cross = 2 minutes
1-min guy returns with flashlight = +1 minute = 3 minutes
5-min guy & 10-min guy cross = +10 min = 13 min
2-min guy returns w/ flashlight = +2 min = 15 min
1-min guy & 2-min guy cross = +2 min
TOTAL = 17 minutes

they are crossing a bridge at midnight with 1 flashlight. and one guy has to go back to get another person since they only have 1 flashlight. same concept >.< you should have made them P.M. AND more than one prize. like 2-5 places get prizes or something. hmm i'll P.M. you anyways

Edit: what happened to the original thread that Zeratul started?

 

Re: Brain teaser / riddle / quiz...

you weren't the first to post

 

Re: Brain teaser / riddle / quiz...

no shit
i mean when posted, and it brought me back to the thread in its entirety, the only thing in ImaGiNe's post was:

 

Re: Brain teaser / riddle / quiz...

god danmit..I hate when I am late for these things. Congrats to whoever solved it!

 

Re: Brain teaser / riddle / quiz...

yea it was pretty easy. dammit!

 

Re: Brain teaser / riddle / quiz...

ImaGiNe. is the first to post a reply with the correct answer.  Even though it was edited, the time of last edit still appear to be earlier than Nikzad's first reply.  However, ImaGiNe.'s final edit and Nikzad's first reply are posted almost simultaneously, being only 20 seconds apart.  So out of fairness and consideration to things like latency, I am declaring both of them winners.

Congratulations to ImaGiNe. and Nikzad.  I have sent 1000 minerals each to both posters.

What original thread?  Zeratul already posted this same brain teaser?  Oh noes~!!  >.<

EDIT  ============================================================================

I got a few more animal related ones, I'll put them up.  I guess I'll make this Remy's puzzle corner.

I'm going to post one at a time and wait for a reply with the correct answer, then post the next one and so on.  I will not be acknowledging posts with edits anymore, only unedited replies will count.  Do not PM me with answers, replies only.

Ok, here we go.

"How do you get a giraffe into a refrigerator?"

I'll start with 50 minerals on this one and go up from there.  50 minerals to the first unedited reply with the correct answer, good luck.

Re: Brain teaser / riddle / quiz... UPDATED 07/04

1.you freeze the giraffe,
2. then you chop it up into little cubs
3. open the fridge
4. neatly stack them inside the refrigerator.
5. close fridge

 

Re: Brain teaser / riddle / quiz... UPDATED 07/04

WOW! I never thought I would hear this one again!

First you open the door of the refrigerator, put the giraffe inside, then close it.

Goooooo Elementary!

Re: Brain teaser / riddle / quiz... UPDATED 07/04

GuiMontag's answer is close enough. I don't know about any frozen cubes but the answer is open door, take out the giraffe, put in the elephant, close the door.

Congratulations to GuiMontag, winner of 100 minerals.

Since we're doing animals, let's stay on that theme. Here's the next one for 150 minerals.

"Lion, the mighty king of beasts and all animals, decided one day to hold a grand meeting. He then proceeded to summon all animals in his vast kingdom to come and attend this meeting. Animals great and small, all scurried along and made it to the meeting. The snake was there, the monkey was there, the cow was there, the bear was there, the gazelle was there, the panda was there, the rabbit was there, the chicken was there, the wolf was there. But there was one animal that wasn't there. Who wasn't at the Lion's meeting?"
