Question 1 of 31048fy_heal_CREATE_q152_2027

You are steering 019°T, and a light is picked up dead ahead at a distance of 11.6 miles at 0216. You change course to pass the light 3 miles off abeam to port. If you are making 14 knots, what is your ETA at the position 3 miles off the light?

Question 1 of 31048

🔍 Key Concepts

• Use Speed = Distance / Time to relate your 14-knot speed to how long it takes to move along your track. • Think about the geometry: you want to pass 3 miles abeam (at right angles) from the light, starting from an initial range of 11.6 miles dead ahead. • Picture or sketch the track line and the position where you are abeam of the light to find the distance you actually travel between 0216 and the abeam point.

💭 Think About

• If the light is dead ahead at 11.6 miles and you later want it 3 miles on your port beam, what kind of triangle does that form with your track line? • How can you use the 3-mile closest point of approach and the 11.6-mile initial range to find the along-track distance you travel before reaching that abeam position? • Once you have the distance run along your course, how many minutes does that take at 14 knots, and what clock time does that give, starting from 0216?

✅ Before You Answer

• Make sure you convert distance traveled along your track (in nautical miles) to time in hours and minutes using 14 knots. • Confirm that the 3-mile abeam distance is treated as a perpendicular distance from your track to the light. • Double-check your time addition from 0216 to your computed elapsed time so your final ETA matches one of the choices.
