Answer 1

-1350 ft

Explanation:

Answer 2

The submarine will be located 1350ft below sea level or (-1350ft)

Explanation:

First we must find the distance traveled

`((300)/(1) )((4.5)/(1))`

From this, we are able to calculate that traveled distance of the submarine.

300 x 4.5 = 1350

1350 + 0 (sea level) = 1350

Therefore the distance traveled by the submarine is 1350ft
