Question

Helene, a hiker, starts at an elevation of 33 feet above sea level and descends 46 feet during her hike to base camp. Which describes the elevation of base camp? (1 point)
O 13 feet above sea level
O 79 feet above sea level
• 79 feet below sea level
• 13 feet below sea level

Answer 1

To find the elevation of base camp, we start with Helene's initial elevation of 33 feet above sea level and subtract the 46 feet she descends:

\[
\text{Elevation at base camp} = \text{Initial Elevation} - \text{Descent}
\]
\[
\text{Elevation at base camp} = 33 \text{ feet} - 46 \text{ feet} = -13 \text{ feet}
\]

Since the result is negative, it indicates that base camp is below sea level. Therefore, base camp's elevation is:

**13 feet below sea level.**

So the correct answer is **"13 feet below sea level."**
