## Caption

Most people get this one wrong.

Four people need to cross a bridge at night.

They have one torch, and at most two people can cross at a time. Whoever crosses together moves at the slower person’s speed.

Crossing Times: 1, 2, 7, and 10 minutes.

What’s the fastest they can all get across?

⬇️ Solution

Use the two fastest people to shuttle the torch.

1 & 2 cross → 2 min
1 returns → 1 min
7 & 10 cross → 10 min
2 returns → 2 min
1 & 2 cross → 2 min

Total = 17 minutes

The trick is minimizing how often the slowest people cross.
