Answer:
The elevation of submarine is −1487.5 feet that means the submarine is 1487.5 feet below the sea level.
Step-by-step explanation:
We are given the following information in the question:
A submarine is 1,275.5 feet below sea level.
It dives down 215.5 feet
It rises 125.5 feet.
Finally, the sub dives down another 122.4 feet.
We are given that the sea level is at an elevation of 0 feet.
Elevation of submarine is given by:
\(-1275.5-215.5+125.5-122.4 = -1487.5\)
The elevation of submarine is −1487.5 feet that means the submarine is 1487.5 feet below the sea level.
