Answer 1

Answer:

1. 430m
2. 310m

Explanation:

Given a submarine is floating 50 m below sea level.

Now the submarine goes to a point A further down 380 m.

Now we need find the depth of point A below sea level.

So given 50 m + 380 m = 430 m

Therefore the depth of the point A will be 430 m

Now second part...

From the point A , it rises 120m to another point B

So given 430 m - 120 m = 310 m

Hope it helps...
