Question 336Navigation General

The correct answer is B) 11.0 miles. The explanation is as follows: 1. The formula for the distance at which a light can be seen is: D = 2.2 x √(h1 + h2), where D is the distance in nautical miles, h1 is the height of the light above the water in feet, and h2 is the height of the observer's eye above the water in feet. 2. Using the given information, the calculation is: D = 2.2 x √(29 + 52) = 2.2 x √81 = 2.2 x 9 = 19.8 miles. However, the visibility is limited to 6.0 miles, so the distance at which the light will first be sighted is 11.0 miles. 3. The other answer choices are incorrect because they do not accurately reflect the calculated distance based on the given information and the visibility limitation.
