A vessel steams 3312 miles on course 282°T from LAT 34°24'S, LONG 18°18'E. What is the latitude and longitude of the point of arrival by Mercator sailing?

Correct Answer: Option B — LAT 22°55'S, LONG 43°05'W

Mercator sailing formulas determine the arrival position by calculating the difference in latitude and departure. Using the distance and course, find the change in latitude and the meridional difference. Applying these to the starting coordinates results in an arrival position of LAT 22°55'S, LONG 43°05'W.
