Why not have a thread dedicated to good ol fashion puzzles?


The Rope Bridge:

Four people need to cross a rickety rope bridge to get back to their camp at night. Unfortunately, they only have one flashlight and it only has enough light left for seventeen minutes. The bridge is too dangerous to cross without a flashlight, and it’s only strong enough to support two people at any given time.

Each of the campers walks at a different speed. One can cross the bridge in 1 minute, another in 2 minutes, the third in 5 minutes, and the slow poke takes 10 minutes to cross. How do the campers make it across in 17 minutes?


p.s. Feel free to share your puzzles.

1 min and 2min cross= 2
2min comes back= 2
5min and 10min cross= 10
1min comes back= 1
1min and 2min cross= 2

Total= 17

If the slow poke is so slow because she's morbidly obese, that completely changes the dynamics.

Very true. What is the weight limit of the bridge? :D

Good job FD.

The 1 minute walker carries the 10 minute walker over, then the 2 minute walker carries the 5 minute walker = 3 minutes. New world record.
