Question

From sea level, a submarine descends 92.5 meters every minute. In 15 minutes, how many meters will the submarine be from its starting position?

Answer 1

1387.5 meters

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
