Gidday!
The four members of U2 (Bono, Edge, Adam, and Larry) must cross a bridge in 17 minutes in order to get to their concert on time.
The conditions: 2 people can cross at a time and they walk at the slower person's rate when crossing (Bono - 1 min to cross, Edge - 2 minutes, Adam - 5 minutes, Larry - 10 minutes). They must travel with the one flashlight when crossing.
How can everyone get across within 17 minutes?

soonerfan1372 was the first to get it right.
The other way to do it is to have E (instead of B) come back with the flashlight in the first step, which would then take 4 minutes (instead of 3): In the second step, B would bring back the flashlight and it would only take 11 minutes (instead of 12) for the same grand total of 17 minutes.
