What is the latitude and longitude of your...

🔍 Key Concepts

• How to read latitude and longitude values on a chart (latitude on the sides, longitude on top/bottom) • How your track line and DR (dead reckoning) positions progress with time between fixes • Whether latitude increases/decreases when moving north/south, and longitude increases/decreases when moving east/west in the Western Hemisphere

💭 Think About

• Between your last known fix and 2118, did your vessel move generally north or south, and east or west? How should that change the degrees and minutes of your position? • Compare the distance run and course steered: does the change in latitude look larger or the change in longitude? Which answer choice reflects that proportion of change? • Look at the pattern of your earlier positions: are the minutes of latitude and longitude increasing or decreasing over time? Which option continues that trend at 2118?

✅ Before You Answer

• Verify that the direction of change (increasing/decreasing minutes) in both latitude and longitude from your last known position to 2118 matches the course steered. • Check that the distance run and time interval would realistically produce the size of change in minutes shown in the choice you are considering. • Make sure the chosen position lies on or very close to your plotted track line between the earlier DR/fix and the 2118 position.
