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

rsHwyEvalwas discovered while updating this BARS.rsHwyEval: ((95 - 65) + (1 1/2) + (1/2)) * (1/4) = 8 * These signs were found on I-8.
