🔍 Key Concepts

• Convert the change in latitude and longitude into a distance traveled using appropriate minutes-to-miles relationships • Use the basic speed formula: Speed = Distance / Time, keeping track of hours and minutes • Recognize that one minute of latitude equals one nautical mile and think about how to approximate the effect of longitude change at this latitude

💭 Think About

• How many nautical miles did the vessel move north and how many miles did it move west between the two positions? • Once you have the total distance over the ground, what is the elapsed time in hours between 1035 and 1103, and how does that plug into the speed formula? • Compare your computed speed to the answer choices and see which is closest to your calculated value.

✅ Before You Answer

• Be sure you convert 28 minutes of time correctly into hours before using the speed formula • Confirm your distance calculation combines both the north-south (latitude) and east-west (longitude) components, not just one • Check that you're using nautical miles, not statute miles, when you relate minutes of latitude to distance
