**Five People on Two Bridges**, where we met five people who needed to cross two sequential bridges at night?

In this puzzle, there are *six people* who must cross *three sequential bridges at night*. As in the original puzzle, there are some difficulties on the way. These are furnished hereunder as follows:

- Each of the three bridges have the same length.
- Each bridge can only support two people crossing at a time.
- Each person has a different speed in which they cross each bridge:

1 minute, 2 minutes, 5 minutes, 7 minutes, 10 minutes, and 14 minutes. - If two persons are moving simultaneously, then they must move with the speed of the slower person.
- They have only two flashlights between them to see in the dark.
