Once at the posted coordinates you will observe two speed limit signs.
A = lower of the two number
B = higher of the two numbers
To determine the final coordinates do a projection from posted using the following:
meters = (10 x (A + B - 1))
angle = A + B + B + B - 2
To ensure you have the correct answers for the above the sum of angle and meters is 728.
The last digit of the north coordinates is 9 and the last digit in the west coordinates is 5.
