🔍 Key Concepts

• Speed = Distance / Time relationship and how to rearrange it to find time of voyage • How to convert total travel time in hours into days and hours, then apply it to a calendar date • How to convert between time zones using Zone Descriptions (ZD), especially from ZD +5 at departure to ZD +8 at arrival

💭 Think About

• First, ignore bunkering and canal time. Use the distance and speed of advance to compute the pure steaming time in hours, then add the bunkering and canal delays to get a total elapsed time. • Once you have the total elapsed time in hours, carefully convert it to days and leftover hours. Then add that to the departure local time and date (ZD +5) to find the arrival time in that same ZD. • Finally, convert that arrival time from ZD +5 to ZD +8 by applying the correct sign and number of hours, watching carefully for any date change when you shift time zones.

✅ Before You Answer

• Verify you used Speed (knots) = Distance (NM) / Time (hours) correctly and solved for Time. • Check your arithmetic for converting hours to days plus hours, and for adding days across from November into December. • Confirm that the time zone conversion from ZD +5 to ZD +8 is in the correct direction (are you adding or subtracting hours?), and adjust the date if the clock crosses midnight.
