RE: A82: microsoft test.... see how smart you are...
Heh, lol, that's funny, "i think you mean 19 minutes" :)
No, it can be done in 17.
STOP READING IF YOU WANT TO TRY IT YOURSELF!!
Bono and Edge go together. That's 2 min.
Edge returns with the light. That's 4 min.
Adam and Larry go together. That's 14 min.
Bono returns with the light. That's 15 min.
Finally, Bono and Edge go together. That's a total of 17.
The main strategy I used was making sure that Larry and Adam go together,
then Adam's 5 minutes no longer are a problem, and there's extra time for
moving the flashlight. And of course, the faster guys go first so they can
return the flashlight after the slow guys go.

Funny solution:
Give Larry the steriods that Bono is addicted to. That should cut his time
in half, giving Adam and Larry equal time to get across. Bono goes over
with Larry (5 mins), and then goes and picks up Adam (11 mins). Bono then
goes back and picks up Edge, giving them five minutes to get ready.
Real solution:
Bono has to do most of the work, for once. Bono comes over with Larry,
first (10 mins). Bono then returns and picks up Adam (16 mins), and
finally, Bono picks up the Edge (19 mins). Now, they have to hurry their
butts up.
One question.. I think you mean 19 minutes, as opposed to 17. Do you?
