A vessel at LAT 20°10'N, LONG 122°00'E is to proceed to LAT 26°18'N, LONG 128°20'E. What are the course and distance by mid-latitude sailing?

Correct Answer: Option B — 043.5°T, 507.3 miles

Mid-latitude sailing approximates the Earth as a sphere for short distances. Calculate the difference in latitude and departure, then find the mean latitude. Using these values, determine the course angle and distance. The results are 043.5°T and 507.3 miles, consistent with standard navigation practice.
