Five people come to a river in the night. There is a narrow bridge, it can only hold two people at a time. They have one torch and, because it's night, the torch has to be used when crossing the bridge. Person A can cross the bridge in one minute, B in two minutes, C in four minutes, D in seven minutes, and E in eleven minutes. When two people cross the bridge together, they must move at the slower person's pace. What is the minimum time for them to cross the bridge (in minutes)?
