I see that someone has already beaten me to providing the correct answer of
20 miles. However, I'll add the clay related portion to make this an
official Clayart topic:

This weekend I used those very same figures - in feet instead of miles - to
lay out the corners of our new kiln shed. By measuring from a corner 6 feet
along one wall and from the same corner 8 feet along an adjoining wall, then
checking that the distance between the two end points was 10 feet, I could
tell that the walls were square. Simple, accurate, easy to remember. The
proportions are 3:4:5. Any multiple of that - 6:8:10, 15:20:25, etc - in any
unit will work.

So the walls are up, but the Hilti gun that we rented to shoot the frame
down to the slab didn't work properly. The nails barely penetrated the
concrete. A weather front had just passed through and I was very nervous
about the wind taking everything down before I could get it fastened down.
Fortunately, the wind died down later on and the shed is still standing. New
gun today and we'll try again.

After reading a few of these answers, I think Kelly should put it in
the next skit at NCECA.

Bruce, if you have not yet shot the walls onto your pad then you might
consider using a bit more time consuming but better method. Layout exactly
where the walls will be on the pad. Then either rent, borrow or buy a
rotarty drill (often called a hammer drill). Next drill out 1/4" holes
through the bottom plate of your walls while they are in place leaving a
mark on the concrete below. Be carful not to put much pressure on the bit
you are using to drill the wood as you get close to the concrete. If you do
you will very quickly ruin it if you inadverdently attempt to drill into the
concrete, especially if you are using a paddle bit to drill the wood. If
your pad is freshly poured concrete you won't have any problem drilling into
it. If, however, it is an old aged slab then you've got your work cut out
for you. That may be why the nail shooter didn't work.
Now it's time for the hammer drill. Take the drill and drill into the
conrete where the marks are with a 1/4" bit every 16"s or so. You will use a
masonary drill bit to do this. If you rent the drill it will most likely
come with it. It is not an absolute but a "spline" type of hammer drill and
bit work much better than the conventional type of chuck.
Next get yourself the necessary number of cinch anchors and drop them
into the holes (you may need to gently hammer them in a bit.)Replace the
walls over the holes and take the bolts that fit the cinch anchors (they
have little pointed tips) and put nice fat flat washers onto the bolts.
Insert the bolts through the holes in the wood, you will need to use a
socket and ratchet to screw it through the wood and into the cinch anchor
directly below intil it is nice and snug. Don't overtighten or you'll break
the bolt or strip out the anchor. Remember, are there to help prevent a
lateral thrust of the building from occuring primarily.
Hope this helps
