Answer:

\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15} miles

Step-by-step explanation:

Starting at sea level, a submarine descended at a constant rate to a depth of −4/5 mile relative to sea level in 3 minutes.

Total time = 3 minutes

[tex]\texttt{Total depth descended in 3 minutes = }-\frac{4}{5}miles[/tex]

We need to find what was the submarine's depth relative to sea level after the first minute,

\texttt{Depth descended in per minute = }-\frac{\frac{4}{5}}{3}=-\frac{4}{15}miles

\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15}\times 1=-\frac{4}{15} miles\\\\\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15} miles
