Which describes the elevation of base camp?(1 point)Responses236 feet above sea level236 feet above sea level678 feet above sea level678 feet above sea level678 feet below sea level678 feet below sea level236 feet below sea level

Answer 1

To find the elevation of base camp, you start with Lisa's initial elevation and subtract the descent.

Lisa starts at 457 feet above sea level and descends 221 feet:

\[ 457 , \text{feet} - 221 , \text{feet} = 236 , \text{feet} \]

Therefore, the elevation of base camp is 236 feet above sea level.

The correct response is: 236 feet above sea level.
