Question 1 of 2707066636eea28f7522a1c51acb5

From your 2118 position, you are steering 288°T at an engine speed of 7.0 knots. If visibility is suddenly reduced to 2 miles, at what time can you expect Old Point Comfort Light to become visible again?

Question 1 of 27070

🔍 Key Concepts

• Speed-Distance-Time relationship for 7.0 knots and converting hours to minutes • How visibility range (2 miles) relates to when a light becomes visible along your track line • Your 2118 DR position and course 288°T in relation to Old Point Comfort Light on the chart

💭 Think About

• From your 2118 position, estimate the distance along your 288°T track line to the point where you are 2 NM from Old Point Comfort Light. How can the chart help you find that? • Once you know that distance, how do you use Speed = Distance / Time to find how many minutes after 2118 you will reach that 2 NM point? • Look at each answer choice: which ones are before 2118, and which are plausible based on how long it would take to travel a few miles at 7 knots?

✅ Before You Answer

• Confirm the distance (in nautical miles) from the 2118 DR position to the point where your track passes 2 NM from the light. • Compute the time using Time (hours) = Distance (NM) / 7.0 knots, then convert hours to minutes. • Check whether the distance at 2118 is already 2 NM or less; if so, the light could already be visible at 2118, otherwise add the computed minutes to 2118 and compare with the choices.
