🔍 Key Concepts

• Distance to the horizon formula in nautical miles using height in feet • How to combine the observer’s height of eye with the object’s height to get geographic range • Using square roots and checking which multiple‑choice answer is closest to your computed value

💭 Think About

• First, find the distance to the horizon from your height of eye alone; then, separately, from the mountain’s height alone. How are these two distances used together? • Think about the standard constant used with height in feet to get distance in nautical miles. Are you using the correct constant and units? • Once you compute your approximate total distance, which option is closest to your result?

✅ Before You Answer

• Make sure you are using heights in feet, not meters, in the horizon-distance formula • Confirm that you are taking the square root of each height before multiplying by the constant • Verify that you add the two horizon distances (your eye height and the mountain’s height) before comparing to the answer choices
