You are on a voyage from Corpus Christi, TX to Fort de France, Martinique. The distance from pilot to pilot is 2190 miles (2521 statute miles). The speed of advance is 15.0 knots. You estimate a layover in Charlotte Amalie, Virgin Islands, of 16.0 hours. If you take departure at 0654 (ZD +6), 27 November, what is your ETA (ZD +4) at Fort de France?

Question

Accepted Answer

Option C: 0254, 4 December. Calculate steaming time (2190 nm / 15 kts = 146 hours) and add the 16-hour layover, totaling 162 hours (6 days, 18 hours). Adjust for the time zone change from +6 to +4 (2 hours earlier). Adding 6 days, 16 hours to the departure time results in 0254, 4 December.
