A vessel at LAT 20°00'N, LONG 107°30'W is to proceed to LAT 24°40'N, LONG 112°30'W. What is the course and distance by mid-latitude sailing?

Correct Answer: Option D — 315.3°T, 394.0 miles

Mid-latitude sailing formulas resolve difference of latitude, departure, and corrected middle latitude. Applying standard traverse tables and trigonometric functions from Bowditch produces a course of 315.3 degrees True and a distance of 394.0 miles.
