Given data:

The given rate of the submarine is r=7 feet per second.

The given time is t=30 seconds​.

The given expression for the distance is,


d=r* t

Substitute the given values in the above expression.


\begin{gathered} d=(7\text{ ft/s)(30 s)} \\ =210\text{ ft} \end{gathered}

Thus, the altitude is 210 feet.
