Question

A submarine started the day at 1200 feet below sea level. The submarine rose 60 feet per hour during a 3-hour period. Which expression represents the new position of the submarine in relation to sea level? –1,200 – 3(60) –1,200 + 3(60) 1,200 – 3(60) 1,200 + 3(–60)

Answer 1

The answer is -1200 +3(60)

Answer 2

Answer:

The answer is -1200 +3(60)

Step-by-step explanation:

If the submarine is 1200 feet below sea level, that means that the submarine's level is -1200. If you rise by 60 in a 3 hour period, you rise by 60 every 3 hours. So if your rising by 60 feet, 60 is not a negative, and the equation would be -1200+3(60). Hope this helped! :D
