BARS::Space Shuttle Somewhere in Virginia

MathBabbler saw these road signs on Facebook.

The road signs say...

   +---------------------+ +---------------------+
   | South VA-28 to I-66 | | North VA-28 to VA-7 |
   |     Centreville     | |    Dulles Airport   |
   |    Exit 1/4 Mile    | +---------------------+
   +---------------------+ 
                           +-------------+
                           | Exit 20 MPH |
                           +-------------+
   the numbers are:  28  66  1/4  28  7  20

   the math is:  (66 * sqrt(1/4) - 28) * 28 / 7 = 20

   more math:  (20 / (1/4) - 66) * sqrt(28 / 7) = 28

   rsAgeEval:  66 - 20 + 28 * (1/4) + sqrt(28 / 7) = 55
   * MathBabbler was 55 years young when he saw these signs.

   rsAgeEval:  66 - ((1/4) * 20) - 7 + 28 / 28 = 55
   * MathBabbler was 55 years young when he saw these signs.
