DESCRIPTION

Four people are crossing a bridge at night, so they all need a torch—but they just have one that only lasts 15 minutes. Mike can cross in one minute, Ben in two minutes, Laura in five minutes and Daniel in eight minutes. No more than two people can cross at a time; and when two cross, they have to go at the slower person’s pace. How do they get across in 15 minutes?
