    There are 4 people that are going to cross a wooden bridge. They must cross in 60 minutes. They can only can cross 2 at time. It is dark and they only have 1 lantern so once 2 cross one must go bring the lantern back. Here are the times it takes for each person to cross the bridge: 25 minutes, 20 minutes, 10 minutes, and 5 minutes. How can they cross in time?
