Answer 1

To find your new elevation after climbing up from the Dead Sea, you need to add the elevation change to the current elevation.

Current elevation at the Dead Sea = -1,410 feet
Climbing up = +125 feet

So, the calculation is:

\[ -1,410 + 125 = -1,285 \]

Your new elevation after climbing 125 feet is -1,285 feet (negative 1,285 feet).

The correct response is:

−1,285 feet (or negative 1,285 feet).
