There is 4 of you. You and three other friends. I will name your friends as A, B, C and yourself as U. You all are on an island and the island has a volcano. The volcano is about to explode, so you will have to leave. The only way off the island is by crossing over a 100ft broken bridge, it is nightime but you have a torch. There are Alligators at the bottom of the bridge who are waiting for one of you to fall. To cross the bridge it takes;
A 8 mins
B 5 mins
C 2 mins
U 1 mins
Giving you a total of 16mins. I need you to all cross the bridge in 15mins. Only 2 of you can go at anyone time and 1 person has to come back with the torch. You cannot take 3 in anyway and there is no catch to it. It is possible to take you all 4 across in 15mins.
If 8+5 go that will take 8 minutes and 5 returns that is 13 mins
If 2+5 go it will take you 5 mins and 2 returns that is 7 mins.
Keep adding and let me know how you get on.
