Puzzle #15: Fire at Red Sea Tech



Solution to be posted next week, or submit your own!

I've added hints to last week's puzzle and extended the answering period. There's still about half of the answers floating out there.

I like the sheer contrast in difficulty between the two most recent puzzles. Yes, this is definitely an 'Easy.'

I am assuming that since there is no mention that the hose must run along the lines of the grid that the puzzle must be solved using the Pythagorean Theorem.

As a result, I came up with that the 125 foot hose would be long enough:

+ 38.08 feet from the hydrant to the bottom right corner of the "other building" (the one in the top left)

+ 26.92 feet from the bottom right corner of the "other" building to the top left corner of the "L" shaped building (note that combining these first two additions makes an exact 65 feet which would also be the result if the calculation was done from the hydrant to the top left corner of the "L" shaped building"

+ 30 feet across the top of the "L" shaped building to the top right corner of it

+ 21.21 feet from the top right corner of the "L" shaped building to three squares over and three squares down

= 116.21 feet total

Assuming that I am close enough to the fire the 125 foot hose works. Even if I needed to get a little closer than I mentioned the 125 foot hose would still get me there if even another full square was required (as the diagonal of each square is just over 7 feet long).

You would truly show off your rookie status as a fireman if you ran the hose along the grid. (:

Yep, that's correct, it's a simple Pythagorean problem. I figured you guys could use a break after last week's.

Thanks for your consideration Hawkins. =D I am still scratching my head over the last 3 "leftover" answers from last week's puzzle.
