Choose the correct answer
A
46+58
B
46+85
C
47+12
D
47+35
Correct Answer
B. 46+85
Why is this the answer?
Tangent length T = R tan(Δ/2) = 1200 * tan(17.5°) = 377.5 ft. Curve length L = R * Δ(rad) = 1200 * (35 * π / 180) = 733.0 ft. PC station = PI - T = 4500 - 377.5 = 4122.5. PT station = PC + L = 4122.5 + 733.0 = 4855.5, which is station 48+55.5. Given the options provided, the calculation logic in the original explanation was fundamentally flawed and the provided options were incorrect for the given parameters.
