BARS::40 St. Exit on I-10 East in Phoenix, Arizona

This road sign was found approaching the 40th Street exit on eastbound I-10 in Phoenix, Arizona.

The road sign says...

   +----------------------------+
   | 40th St                1/4 |
   | 143 - 48th St        1 1/4 |
   | Broadway Rd                |
   | Jct 60                   3 |
   +----------------------------+

   the numbers are:  40  (1/4)  143  48  (1 1/4)  60  3

   the math is:  (143 + (1 1/4) - (1/4) x log(sqrt(40 + 60))) / 3 = 48

   observe...
      sqrt(40 + 60) = sqrt(100) = 10
      log(10) = 1
      143 + 1 1/4 - 1/4 = 144
      144 x 1 = 144
      144 / 3 = 48
