A vessel at LAT 07°05'N, LONG 81°45'W is to proceed to LAT 08°40'N, LONG 88°00'W. What are the course and distance by mid-latitude sailing?
Official USCG Answer & Rule Citation
Correct Answer: Option D — 284.3°T, 384.6 miles
Middle-latitude sailing formulas relate departure and arrival coordinates using mean latitude ($L_m$). Applying Bowditch formulas, the latitude and longitude differences yield a course of $284.3^\circ\text{T}$ and a distance of $384.6$ miles between the specified waypoints.
