This is the ‘bridge and torch’ problem, an example of the wider category of ‘river crossing puzzles.’ Read about other examples and their history here. Variations of the problem have appeared for decades, each with different numbers and times, but it is possible to work out a formal mathematical solution for any of the values you plug in.

Variations of the puzzle have even been used to test computer programming languages for their usefulness in problem-solving. Can you think of any other reason you may want to challenge yourself with similar puzzles?
