There are 5 people on one side of a bridge at night. They need to cross, but they only have one light. They can cross the bridge two at a time, but someone must bring the light back after each trip. Each person travels at a different speed across the bridge.
Person #1 - 1 second
Person #2- 3 seconds
Person #3 - 6 seconds
Person #4- 8 seconds
Person #5- 12 seconds
What is the fastest time possible for all the people to get across the bridge? The people must walk on their own, they cannot be carried.
Good luck!
