a small submarine is at -1,320 feet in relation to sea level. the submarine needs to be at 180 feet below sea level in 60 minutes. another submarine is at -1,440 feet, and also needs to be at 180 feet below sea level in 60 minutes. how much faster does the second submarine need to travel

the answer to this question is in the pic

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer: y = -2.5x - 15

              (-6,0)

answer:

24pi or letter c
