There are some areas of land on Earth that are below sea level. Imagine you are at the Dead Sea in Africa, which has an elevation of about −1,410 feet (1,410 feet below sea level). You then climb up 125 feet. What is your new elevation?(1 point)
Responses
1,285 feet
1,285 feet
−1,335 feet
negative 1,335 feet
−1,535 feet
negative 1,535 feet
−1,285 feet
negative 1,285 feet
To find the new elevation, you need to add the change in elevation to the initial elevation:
−1,410 feet + 125 feet = −1,285 feet
Therefore, your new elevation is negative 1,285 feet.
