53. You depart LAT 25°54'N, LONG 9°38'E and steam 592 miles on course 270°. What is the longitude of arrival?
Steaming west on a constant latitude decreases longitude. The change in longitude is calculated by dividing the distance traveled by the cosine of the latitude multiplied by 60. This results in a longitude of 120'W.
