A submarine is is 250 feet below sea level. It descended another 130ft. How many feet below sea level is the submarine now?

380 feet below sea level.

Step-by-step explanation:

Given:

A submarine is is 250 feet below sea level.

It descended another 130 feet.

Question asked:

How many feet below sea level is the submarine now?

Solution:

A submarine is initially below the sea level = 250 feet

Another descend below the sea level = 130 feet

Now, we have to calculate the final level of submarine below the sea level and for it we will simply add initial level to the another descended depth:-

250 feet + 130 feet = 380 feet.

Therefore,  submarine is now 380 feet below sea level.
