Answer:
The first submarine needs to travel at a rate of [-180 – (-1,320)] ÷ 60 = 19 feet per minute.
The second submarine needs to travel at a rate of [-180 – (-1,440)] ÷ 60 = 21 feet per minute.
21 – 19 = 2, so the second submarine must travel 2 feet per minute faster than the first sub.
C because they all have to add up to 180 and 20+130=150 and 180-150=30
