ok, four people need to get to a place in 17 minutes, and they all must cross a bridge to get there. All four men begin on the same side of the bridge. You must help them across the other side. It is night. There is only one flashlight. A maximum of two people cross the bridge one time. Any party who crosses, either 1 or 2 people, must have a flashlight with them. The flashlight must be walked back and forth, it can not be thrown, etc. Each person walks at a different speed.

A pair must walk together at the slower man's mace

Person 1: 1 minute to cross
Person 2: 2 minutes to cross
Person 3: 5 minutes to cross
Person 4: 10 minutes to cross

thats the problem, which, I've been thinking for an hour and haven't seemed to figure it out, thanks in advance.

What's wrong with the bridge? Why can't the light be thrown? Where's the moon?
The will to neither strive nor cry,
The power to feel with others give.
Calm, calm me more; nor let me die
Before I have begun to live.

-Matthew Arnold

Arguments are to be avoided; they are always vulgar and often convincing.

IDK, we asked my math teacher that and he's like, IDK, just do the problem.

Tell him it's a problem with no damn relevance to real life and is completely absurd, and you don't think your time should be wasted with it. Try solving a real problem, like poverty.

Person 1 and Person 2 cross together with the flashlight (takes 2 minutes).

Person 1 returns to the original side (takes 1 minute).

Person 3 and Person 4 cross together with the flashlight (takes 10 minutes).

Person 2 returns to the original side (takes 2 minutes).

Person 1 and Person 2 cross together with the flashlight (takes 2 minutes).

add them together and wow its 17 minutes

easy

1. 1 and 2 cross
2. 2 comes back
3. 5 and 10 cross
4. 1 comes back
5. 1 and 2 cross

the point of the problem is that the four guys have 17 minutes to get somewhere and its across the bridge. my math teacher used U2 getting to their concert on time as an example.

yeah he used U2 as an example too, I just didn't want to bring it up, or there be more people posting about U2. Everyone in my class was like, it's U2 why the hell would they be walking to their concert, and I said why the hell would they be getting there when it starts, they have to at least warm up a little before going out on the stage.

person 1 and 2 goes over (2mins)
person 1 comes back (1min)
person 3 and 4 goes over (10mins)
person 2 comes back(2mins)
person 1 and 2 go over(2 mins)
total = 17mins

edit: woah i spend half and hour in front of the computer to get this and in that time so many had beaten me!!
