Answer:
Step-by-step explanation:
The question is not well structuredand lack some information.
Restructured:
Another submarines dissent can be modeled as Y= -250 X, where Y is the vertical position and X is the. access time in hours. How long will it take the submarine to make dissent of -200ft?.
To get the time taken to dissent -200ft., we will have to substitute
Y = -200ft into the given expression as shown;
Y = -250X
-200 =-250X
Rearrange
-250X = -200
-25X = -20
Divide both sides by -25
-25X/-25 = -20/-25
X = 20/25
X = 4/5 hrs
Convert to minutes
X = 4/5 × 60
X = 4×12
X = 48minutes
Hence submarine will take 48minutes to dissent -200ft
