Question

Helene, a hiker, starts at an elevation of 24 feet above sea level and descends 31 feet during her hike to base camp. Which describes the elevation of base camp?
Responses

7 feet above sea level
7 feet above sea level

7 feet below sea level
7 feet below sea level

55 feet below sea level
55 feet below sea level

55 feet above sea level

Answer 1

To find the elevation of base camp, you need to subtract the descent from Helene's starting elevation.

Starting elevation: 24 feet above sea level
Descent: 31 feet

So, the calculation is:

24 feet - 31 feet = -7 feet

This means base camp is 7 feet below sea level.

Therefore, the correct response is:

7 feet below sea level.
