At 0915 zone time on 7 November you depart Seattle, LAT 47&deg;36.0'N, LONG 122&deg;22.0'W, (ZD +8). You are bound for Kobe, LAT 34&deg;40.0'N, LONG 135&deg;12.0'E, and you estimate your speed of advance at 18.5 knots. The distance is 4,527 miles. What is your estimated zone time of arrival at Kobe?

Accepted Answer

Option B: 0657, 18 November. Calculate travel time by dividing distance (4,527 nm) by speed (18.5 knots), totaling 244.7 hours (10 days, 4 hours, 42 minutes). Account for the time zone change from +8 to -9, a 17-hour advance. Adding these to the departure time results in an arrival of 0657 on 18 November.
