# Riddle: 4 Men and the Bridge

Try to work out the solution yourself, there will be spoilers in Comments – Don’t scroll down if you want to try and solve it yourself!

Remember that if any of the men cross the bridge and there are still some men (or man) left behind, one of those men who has crossed needs to go back with the torch, as the men (man) left behind cannot cross the bridge without it.

If two of the men cross the bridge, then the time it takes for them to cross the bridge is the time it takes for the slower person.

Solution video is here: https://www.youtube.com/watch?v=udjN9xyW6MA – Did you manage to solve it?

Yes, I know the bridge that I drew (I’m ever so brilliant at art, aren’t I?) isn’t long. Just imagine that it is and carry on with the riddle!

Pause the video whenever you need to, to take down the details. The solution is quite simple and you just need to put your mind to it. NO CHEATING!! Try and find the fastest time you can come up with before you start searching the web for solutions.

Have Fun! 😀

Also I cant cross the bridge with guy 1 because his wolf will eat my chicken

The sum of all the people's times are 18. Since they cannot go any slower than their time an they all must cross the bridge then it is impossible to do it in 17 minutes. Am I wrong? …….

Heres another way. The two fastest cross the bridge. 1 then takes the lanter over then let the two slowest cross it. Then 2 takes the lantern then comes to you and guides you to the other side. Thats equal to 17 minuetes

1 steals the flashlight and beats up the others they are very weak except 1.2 is critically injured while 3&4 are unconscious. 1 feels bad about his actions and calls his mom and jumps off the bridge. But what's this? 2 crawls all the way over the bridge 2 is suffering from hypothermia. 3&4 had died by a lion. 2 gets up and runs to the nearest car. He finds a spare key inside the car and closes and locks the car door. 2 is now unconscious. Then it is daytime and 2s car gets towed. DUNDUNDUNNN 4 is the guy in the tow truck 4 is a survivor! But where is 3

1 and 2 go, then they throw the flashlight to 5 and 10, but it falls under the bridge, so they all get abandoned.

• September 21, 2017 at 12:16 pm

1 kills 5,10 then 1 grabs 2's hand and they crossed the bridge then they married – 3 mins easy

• September 21, 2017 at 12:16 pm

10 Takes 5 across 5 comes back and brings 2 across and 2 goes back to bring 1 across and 1 brings back the torch so 2+5+10=17
