One for the Logic heads, it's stumped me......
U2 have to cross a river with a boat that holds two people. The slower
rower on the boat determines the speed of the
crossing. The individual speeds are:
Bono: 1min
Edge: 2 min
Drummer: 5 min
Adam: 10 min.
(For instance, if Bono and Edge go together, it takes them two minutes but
if Edge goes with Adam, it will take them ten
They manage in 17 minutes (including return trips). How?

any ideas?
