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. What

Helga [31]

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

$\texttt{Total depth descended in 3 minutes =}-\frac{4}{5}miles$

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

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

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