If you are steering 163 degrees T and the light is 11 nautical miles away, what is your ETA at a speed of 13 knots from the observation time 0142?

To determine the estimated time of arrival (ETA), it is important to consider the distance to the light and the speed of the vessel. In this scenario, the light is 11 nautical miles away, and the vessel is traveling at a speed of 13 knots.

First, you calculate the time it will take to cover the distance to the light. This is done using the formula:

Time (hours) = Distance (nautical miles) / Speed (knots).

By substituting the given values into the formula:

Time = 11 nautical miles / 13 knots = 0.846 hours.

To convert this time into minutes, multiply by 60:

0.846 hours × 60 minutes/hour ≈ 50.76 minutes, which rounds to about 51 minutes.

Next, you add this time to the current time of 0142. Adding 51 minutes to 0142:

• Adding 51 minutes to 42 minutes gives you 93 minutes, which is more than 60.
• Therefore, you convert to hours: 93 minutes - 60 minutes = 33 minutes into the next hour.
• The time will transition into 0300 (the next hour), and then you add the
