You are making 12 knots and you see a light dead ahead at a distance of 14 nautical miles. What will be your ETA if the light is observed at 1037?

To determine the estimated time of arrival (ETA) at the light, the key is to calculate the time it takes to travel the distance at the given speed. In this scenario, you are traveling at 12 knots and the light is 14 nautical miles away.

First, calculate the time it will take to cover the 14 nautical miles. Since speed is given in knots, which is nautical miles per hour, you can use the formula:

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

Substituting the known values:

Time = 14 nautical miles / 12 knots = 1.1667 hours.

To convert the decimal hours into minutes, take the decimal part (0.1667) and multiply by 60:

0.1667 hours × 60 minutes/hour = 10 minutes.

So, the total travel time is approximately 1 hour and 10 minutes.

Now, to find the ETA, add this travel time to the observation time of 1037.

Adding 1 hour to 1037 brings you to 1137. Then add the 10 minutes, resulting in 1147. This calculation shows that you will arrive at the light at 114
