I'm pretty sure it would be -5/24

Answer:

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

Step-by-step explanation:

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

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

= [tex]\frac{\text{Rate at which submarine is descending}}{\text{Time taken}}[/tex]

= [tex]-\frac{5}{6\times 4}[/tex]

= -[tex]\frac{5}{24}[/tex]

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