BARS::Attractive Numbers, But Tough Math Near Sedona, Arizona

This road sign was located on AZ Hwy-179 south of Sedona, Arizona.

The road sign says...

   +-----------------------+
   | Sedona             15 |
   | Oak Creek Canyon   25 |
   | Flagstaff          45 |
   +-----------------------+

   the numbers are:  15  25  45

   the math is:  floor(sqrt((15 x 45)) = 25

   observe...
      15 x 45 = 675
      sqrt(675) = 25.981
      floor(25.981) = 25

   dup(15)... the numbers are:  15  15  25  45
              the math is: 15 / sqrt(25) x 15 = 45

   dup(25)... the numbers are:  15  25  25  45
              the math is:  sqrt(45 / sqrt(25)) x sqrt(25) = 15

   dup(45)... the numbers are:  15  25  45  45
              the math is:  sqrt(45 / sqrt(25)) x 15 = 45
