Question 1 of 27070

At 0728, Race Rock Light is bearing 282°T at 3.8 miles, and the closest point on Fishers Island has a radar range of 2.1 miles. What speed have you been making since you changed course at 0705?

🔍 Key Concepts

• Speed = Distance / Time relationship and converting minutes to hours • Using the time interval between 0705 and 0728 to find elapsed time • Interpreting the given ranges (3.8 miles and 2.1 miles) to determine total distance run

💭 Think About

• How many minutes have passed between the time you changed course and the time of the second observation? How do you express that in hours? • Which of the given distances (3.8 miles and 2.1 miles) represents how far you have actually traveled along your track since 0705? Is it one of them, their difference, or their sum? • Once you have the distance traveled and the elapsed time in hours, what does the basic speed formula tell you about your speed in knots?

✅ Before You Answer

• Be sure you are using elapsed time in hours, not in minutes, when computing speed in knots • Verify that the distance you use is along track, not just a lateral distance or separation between two objects • After computing speed, compare your result with the answer choices and select the closest matching value
