You depart LAT 16°24'S, LONG 169°38'W, for LAT 16°24'S, LONG 174°52'E. What are the course and distance by parallel sailing?

Correct Answer: Option A — 270°T, 892 miles

Parallel sailing applies when navigating along a constant latitude circle across varying meridians. Distance is calculated using $D = \Delta \lambda \times \cos(Lat)$. Crossing the 180th meridian from 169°38'W to 174°52'E gives a 300-mile $\Delta \lambda$, yielding 892 miles true west.
