Lisa, a hiker, starts at an elevation of 457 feet above sea level and descends 221 feet during her hike to base camp. Which describes the elevation of base camp?

Question

236 feet below sea level
236 feet above sea level
678 feet below sea level
678 feet above sea level

Answer 1

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

Starting elevation: 457 feet Descent: 221 feet

Elevation of base camp = Starting elevation - Descent Elevation of base camp = 457 feet - 221 feet = 236 feet

Since the resulting elevation is above sea level, we conclude that base camp is 236 feet above sea level.

So, the correct answer is: 236 feet above sea level.
