You are steering 107°T, and a light is picked up dead ahead at a distance of 11 miles at 0847. You change course to leave the light 3 miles off to starboard. If you are making 15.5 knots, what is your ETA at the position 3 miles off the light?

You are steering 107&deg;T, and a light is picked up dead ahead at a distance of 11 miles at 0847. You change course to leave the light 3 miles off to starboard. If you are making 15.5 knots, what is your ETA at the position 3 miles off the light?

Accepted Answer

Option A: 0928. Determine the distance to the abeam point using the Pythagorean theorem: square root of (11 squared minus 3 squared) equals 10.58 miles. Dividing this distance by the speed of 15.5 knots results in 41 minutes of travel time, establishing an ETA of 0928 at the abeam position.
