A vessel at LAT 28°00'N, LONG 116°00'W is to proceed to LAT 34°00'N, LONG 123°40'W. What is the course and distance by mid-latitude sailing?

Correct Answer: Option A — 312°T, 533 miles

Per Bowditch guidelines, mid-latitude sailing determines course and distance by substituting mean latitude into departure calculations ($p = D\text{Lo} \cos L_m$). Solving the right triangle for these coordinates gives $312^\circ\text{T}$ and $533$ miles.
