A mountain peak charted at 700 feet breaks the horizon, and your height of eye is 12 feet. What is your approximate distance off (choose closest answer)?

Correct Answer: Option A — 34.7 nm

Geographic range is calculated using the formula D = 1.17 * (sqrt(h1) + sqrt(h2)). With a 700-foot mountain and 12-foot height of eye, the calculation is 1.17 * (sqrt(700) + sqrt(12)), resulting in approximately 34.7 nautical miles. This method is standard in Bowditch for determining visibility distances.
