juliecamdotnet: If two cars were faced away from each other back to back, both cars travelled 8 miles forward then made a 90 degree left turn and traveled another 6 miles, how far apart would they be?

   [C]_____                ,
       (6) |               |\
           | (8)           |  \
           |               |    \
           S          (16) |      \  (x)
           |               |        \
       (8) |               |          \
           |_____[C]       |____________\
             (6)                (12)

So, the distance from one car to the other would be the hypotenuse of a right triangle with sides measuring 16 and 12 miles.

162 + 122 = x2
256 + 144 = x2
400 = x2
20 = x

I get 20 miles (32.19 km)
