Question

6. A submarine is traveling 200 feet below sealevel. It then ascends 75 feet. What is thenew position of the submarine? Write andsolve an equation to represent the situation.

Answer 1

Let d denote the position of the submarine

Now, A submarine is traveling 200 feet below sea level

`d=-200`

It then ascends 75 feet.

`\begin{gathered} d=-200+75 \\ d=-125 \end{gathered}`

Therefore, the submarine new position is 125 feets below sea level
