"U2 puzzle
U2 has a concert that starts in 17 minutes and they must all cross abridge to get there. All four men begin on the same side of the bridge.You must help them across to the other side. It is night. There is oneflashlight. 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 band member walks at a different speed. A pair must walk together at the rate of the slower man's pace:
Bono:- 1 minute to cross
Edge:- 2 minutes to cross
Adam:- 5 minutes to cross
Larry:- 10 minutes to cross
For example: if Bono and Larry walk across first, 10 minutes have elapsedwhen they get to the other side of the bridge. If Larry then returns withthe flashlight, a total of 20 minutes have passed and you have failed themission.
Can you get them across in 17 minutes?"
edit:// Larry takes 10minutes
