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)?

A 34.7 nm
B 40.3 nm
C 55.3 nm
D 61.6 nm
AI Explanation

The correct answer is A) 34.7 nm. The formula to calculate the distance to the horizon is: d = 1.17 * √h, where d is the distance in nautical miles (nm) and h is the height of the observer's eye in feet. Given that the mountain peak is charted at 700 feet and the height of eye is 12 feet, the distance to the horizon is approximately 34.7 nm. This is the closest answer choice. The other options are incorrect because they do not accurately reflect the calculated distance based on the provided information.
