My answer to the Burning Island puzzle

The puzzle is as follows:

A man is stranded on an island covered in forest.

One day, when the wind is blowing from the west, lightning strikes the west end of the island and sets fire to the forest. The fire is very violent, burning everything in its path, and without intervention the fire will burn the whole island, killing the man in the process.

There are cliffs around the island, so he cannot jump off.

How can the man survive the fire? (There are no buckets or any other means to put out the fire)

The answer they gave is that he set another fire to survive, but dies anyway due to starvation. I have a more practical solution.
Because the island is in the middle ocean (Where else would it be?) there will normally be a heavy amount of rain. The rain provides the  intervention by dousing the areas that haven't caught fire yet while not putting out the fire. The fire gradually dies down due to the lack of dry materials and constant dousing by rain and goes out due to lack of fuel. The man survives the fire, builds a raft and returns to civilization.

And that is my answer. (I'm trying to be optimistic.He died in the original answer.)

Re: My answer to the Burning Island puzzle

I think the first answer is what most people use.

As for the second answer, what about the cliffs?

That's a bit far-fetched, don't you think?

Because the island is in the middle ocean (Where else would it be?)

Florida has thousands of islands within eyeview. There are also desert islands.

Re: My answer to the Burning Island puzzle

The man goes to the eastern end of the island and, using his axe, chops down several trees, which he uses to climb down the cliffs. He then floats away clinging to a log, using a stick and the string and fishhook he has with him to catch food. He uses his handy portable desalination kit to obtain potable water, and the AK-47 to fend off sharks. After several days of drifting, he uses his waterproof flashlight to signal a passing ship, and is rescued.

hi applejuicefool

Welcome to the forum!

Thanks for your answer.  I see now that your solution is the obvious one.  Amazing that we all missed it.
