Hi all you weekend riddlers!
Heres a fun one to think about
Its a little bit of logic and a little bit of math.. (but not too much!)
Here we go.....(please pm your answers!)
There are 4 men who want to cross a bridge.
They all begin on the same side.
You have 17 minutes to get all of them across to the other side.
It is night. There is one flashlight. A maximum of two people can cross at one time.
Any party who crosses, either 1 or 2 people, must have the flashlight with them.
The flashlight must be walked back and forth, it cannot be thrown, etc.
Each man walks at a different speed.
A pair must walk together at a rate of the slower man's pace.
Man 1: 1 minute to cross.
Man 2: 2 minutes to cross.
Man 3: 5 minutes to cross.
Man 4: 10 minutes to cross.
For example, if Man 1 and Man 4 walk across first, 10 minutes have elapsed when they get to the other side of the bridge.
If Man 4 returns with the flashlight, a total of 20 minutes have passed, and you have failed the mission.
