Cross The Bridge

---

There are 4 men on one side of a bridge.

Alan can cross the bridge in 1 minute, Bob in 2 minutes. It takes Chuck 5 minutes and Doug needs 10 minutes to get across.

It's dark, and a flashlight is needed to cross the bridge. But between them they have only one. Its batteries will only last another 17 minutes.

The bridge is old and not very sturdy. So they can only cross individually or with one other person. If two people cross together, they walk at the pace of the slower person.

How can they all get across in 17 minutes?
