ANSWER:

28/158

STEP-BY-STEP EXPLANATION:

We have the following information:

Submarine is descending at a constant rate: 58 miles in 316 minutes.

To calculate the depth in the first minute, we make the following proportion:

[tex]\begin{gathered} \frac{58}{316}=\frac{x}{1} \\ \text{solving for x:} \\ x=\frac{58}{316}=\frac{29}{158} \end{gathered}[/tex]
