This road sign with speed limit sign is on eastbound I-8 in Yuma, Arizona. RoadHacker took this picture while wandering downtown Yuma.

The road sign and speed limit sign say...

```   +------------------------+
| Redondo Ctr Dr     1/4 |
| Giss Pkwy              |
| Weigh Station      1/2 |
| 16th St US-95    1 1/2 |
+------------------------+
+-------+
| Speed |
| Limit |
|   65  |
+-------+
```
```   the numbers are:  (1/4)  (1/2)  16  95  (1 1/2)  65

the math is:  ((95 - 65) + (1 1/2) + (1/2)) * sqrt(1/4) = 16

observe...
95 - 65 = 30
(1 1/2) + (1/2) = 2
30 + 2 = 32
sqrt(1/4) = (1/2)
32 * (1/2) = 16

[solve for 'n]  ((95 - 65) + (1 1/n) + (1/2)) * sqrt(1/4) = 16
```
##### Update::2008.10.08

Lindsay, a student at SCC, discovered these same signs while driving east on I-8 in Yuma, Arizona, during the fall 2008 semester. MathBabbler received the dot-jpg file on 7 October 2008. The following rsHwyEval was discovered while updating this BARS.

```   rsHwyEval:  ((95 - 65) + (1 1/2) + (1/2)) * (1/4) = 8
* These signs were found on I-8.
