Answer:
1387.5 meters
Step-by-step explanation:
Sea level is 0
it descends 92.5 m every minute
so the equation will be d=0-92.5m where d is distance and m is minutes
so you want to find out how far it will be after 15 minutes - substitute
d=0-92.5(15)
simplify
d=0-1387.5
solve for d
d=-1387.5
the submarine will 1387.5 meters from its starting position
