A submarine starts at sea level and sinks ⅕ mile. An hour later, it rises ⅕ mile. What is the depth, in miles, of the submarine after the hour

it takes a yard away from the answer so find out the yard in distance

Step-by-step explanation:

minus 1

5/-24

Submarine's depth after first minute will be -\frac{5}{24}

Step-by-step explanation:

Submarine is descending at a constant rate = -\frac{5}{6} miles in 4 minutes

Therefore, after the first minute submarine's depth relative to the sea level will be

= \frac{\text{Rate at which submarine is descending}}{\text{Time taken}}

= -\frac{5}{6\times 4}

= -\frac{5}{24}

Therefore, submarine's depth after first minute will be -\frac{5}{24}

not my answer but hope it helps.
