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?

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!

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

Step-by-step 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
