Dark Bridge


bridge

Four people have to cross a bridge...  It's very dark and they only have one flashlight...  They can't make it across without some light.

No more than two people can cross at a time.

Phil can cross the bridge in 1 minute.
Karen can cross in 2 minutes.
Stinky can cross in 5 minutes.
Bubba can cross in 10 minutes.

How can they all get across in 17 minutes?
