Question

2. A submarine submerged at a depth

of -40 ft dives 57 ft more. What is
the new depth of the submarine?
What is the answer?

Answer 1

If the submarine starts at -40ft below sea level, then we can subtract to find the depth of the submarine when it goes 57ft deeper.

-40 – 57 = -97ft deep or 97ft below sea level.

Best of Luck!

Answer 2

The depth is -97 ft or 97ft below the surface

Explanation:

We start at -40 ft -40

The we go down 57 ft -57

We are at -40-57 = -97

The depth is -97 ft or 97ft below the surface
