70% to pass

What is the approximate geographic range of Southwest Ledge Light, Connecticut, if your height of eye is 32 feet (9.8 meters)? Refer to "Reprints from the LIGHT LISTS AND COAST PILOTS".

A 15.5 nm
B 13.4 nm
C 8.7 nm
D 6.9 nm
AI Explanation

The correct answer is A) 15.5 nm. To calculate the approximate geographic range of a light, you can use the formula: Range (in nautical miles) = 2.23 x (√height of eye in feet). With a height of eye of 32 feet, the formula gives a range of 15.5 nautical miles. The other options are incorrect because they do not accurately reflect the calculated range based on the given height of eye. Option B (13.4 nm) and Option C (8.7 nm) are too low, while Option D (6.9 nm) is significantly underestimated.
