Question

Starting at sea level, a submarine descended at a constant rate to a depth of −58 mile relative to sea level in 316 minutes.The submarine continues to descend at the same rate. What is the submarine's depth relative to sea level after the first minute?Enter your answer as a simplified mixed number

Answer 1

28/158

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:

`\begin{gathered} (58)/(316)=(x)/(1) \\ \text{solving for x:} \\ x=(58)/(316)=(29)/(158) \end{gathered}`
