They all begin on the SAME side.
You have 17 minutes to get all of them across to the OTHER side.
They all must be together on the OTHER side of the log bridge at the end of the 17 minutes.
It is night. There is ONE flashlight. A maximum of 2 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 the 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
