You depart LAT 22°35.0'N, LONG 157°30.0'W, and steam 4505.0 miles on course 135°T. What are the latitude and longitude of your arrival by Mercator sailing?

Correct Answer: Option B — 30°30.5'S, 102°35.3'W

Dead reckoning and Mercator sailing reverse computations from Bowditch use known distance and course to determine the arrival position's latitude and longitude by applying departure offsets across meridional parts.
