On 4 December your 1500 ZT DR position is LAT 18°06.0'N, LONG 75°42.0'W. You are on course 020°T at a speed of 15.0 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 1548 running fix.

Question 1 of 27070

Q

On 4 December your 1500 ZT DR position is LAT 18°06.0'N, LONG 75°42.0'W. You are on course 020°T at a speed of 15.0 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 1548 running fix.

🔍 Key Concepts

• Running fix using DR (dead reckoning) between sights • How far you travel in time using Speed = Distance / Time • Whether both latitude AND longitude should change with the motion described

💭 Think About

• From 1500 to 1548, how many minutes have passed, and what fraction of an hour is that? • At 15 knots, how many nautical miles will you travel in that time, and in what direction will your DR track move your position on the chart? • Given your course 020°T (generally toward north and slightly east), should your latitude increase or decrease, and should your longitude move east or west from 75°42.0'W?

✅ Before You Answer

• Compute the distance run along 020°T between 1500 and 1548 before looking at the choices • Make sure your DR latitude and longitude both reflect motion consistent with 020°T and 15.0 knots • Eliminate any options where either the latitude or longitude has not changed in a way that matches your DR track
