Question

If a submarine is 80 m below sea level if it dives another 15 m, how far below sea level is the submarine now?

Answer 1

Step-by-step explanation

The submarine is initially 80 m below sea level.

It then dives another 15 m.

That means it goes 15 m lower than its original position.

Sea level is equivalent to 0 m.

Therefore, the submarine being initially 80 m below sea level means that it was at -80 m.

Now, it goes 15 m lower,
