Question

The submarine is at an elevation of -355 2/7 feet. The explorers spot a humpback whale and dive downward an additional 92 4/7 feet. The new elevation of the submarine is

feet.

Answer 1

-427 6/7

Explanation:

The new elevation of the submarine is -427 6/7 feet.

What is Elevation?

Elevation is distance above sea level.

Given that;

The submarine is at an elevation of = -355 2/7 feet.

And, Dive downward an additional feet = 92 4/7 feet.

Now, The submarine is at an elevation of feet = -355 2/7 feet.

Hence, First location of submarine= -335 2/7 feet

And, Dive downward for whale = -92 4/7 feet

So, The new elevation of the submarine = -355 2/7 + (-92 4/7)

= -355 2/7 - 92 4/7

= -2347/7 - 648/7

= -2995/7

= - 427 6/7

Answer 2

I believe that the correct answer would be -2995/7 (-427 6/7 in mixed number form) because -335 2/7 minus 92 4/7 is -2995 over 7. I hope this helped.
