🔍 Key Concepts

• Using two fixed positions (fixes) at known times to find speed made good • Converting time in minutes to hours before using the speed formula • Using the basic speed formula: Speed = Distance / Time

💭 Think About

• From 0815 to 0839, how many minutes have passed, and what is that in hours? • On the chart, what is the straight-line distance between your 0815 position and the 0839 position obtained from Montauk Pt. Light bearing 205°T at 6.6 miles? • Once you have that distance, what speed do you get when you divide by the elapsed time in hours, and which choice is closest?

✅ Before You Answer

• Be sure you measure the distance between the two fixes (0815 and 0839), not just the 6.6-mile radar range by itself • Convert 24 minutes into hours correctly before using the formula • Use the formula $\text{Speed (knots)} = \frac{\text{Distance (NM)}}{\text{Time (hours)}}$ and then compare the result carefully with the answer choices
