Answer:
The submarine will be located 1350ft below sea level or (-1350ft)
Step-by-step explanation:
First we must find the distance traveled
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
