You depart LAT 32°16.6'N, LONG 68°28.0'W. What is the course and distance as calculated by Mercator sailing to a position at LAT 43°12.2'N, LONG 55°39.0'W?

Correct Answer: Option C — 042.8°T, 896.2 miles
Mercator sailing determines the rhumb line course and distance. By calculating the difference in latitude and the difference in meridional parts, the course angle is found using the arctangent of (DLong / DMP). The resulting values of 042.8°T and 896.2 miles are correct for the given coordinates.
