BARS::Wahkeena Falls Trail Sign in Oregon

This trail sign was found at Wahkeena Falls in Oregon.

The trail sign says...

   +----------------------------+
   |    WAHKEENA FALLS TRAIL    |
   | Wahkeena Falls    .2 MI -> |
   | Perdition Trail   .5 MI -> |
   | Larch Mt. Trail  3.0 MI -> |
   | <- .5 MI   Multnomah Falls |
   +----------------------------+
   the numbers are:  .2  .5  3.0  .5

   the math is:  .5 / .2 + .5 = 3.0

   [solve for 'n']  .5 / n + .5 = 3.0

   [solve for 'x']  x / .2 + x = 3.0

Just for play, let's multiple each number by 10 and find some math.

	 0.2 * 10 = 2 ...  0.5 * 10 = 5 ... 3.0 * 10 = 30 ... 0.5 * 10 = 5

   the numbers become:  2  5  30  5

   the math is:  (5 - 2)! * 5 = 30

   observe:
      5 - 2 = 3
      3! = 3 * 2 * 1 = 6
      6 * 5 = 30

   more math:  30 - 5^2 = 5

   observe:
      5^2 is 5 raised to the 2nd power... 
      5 * 5 = 25 and 30 - 25 = 5
