At 0915 zone time on 6 March you depart Sydney, LAT 33°51.5'S, LONG 151°13.0'E (ZD -10). You are bound for Kodiak, LAT 57°47.0'N, LONG 152°25.0'W, and you estimate your speed of advance at 21 knots. The distance is 6,222 miles. What is your estimated zone time of arrival at Kodiak?

Correct Answer: Option C — 2132, 17 March

Find steaming duration by dividing distance by speed. Convert departure zone time (-10) to GMT, add elapsed hours, and convert to the arrival zone time at Kodiak (ZD +10). Account for the International Date Line crossing and high-latitude time zone meridians per standard ocean-crossing navigation methods.
