Answer: 42 feet below the sea level

Step-by-step explanation: To solve for the depth, simply just plug in 6 into the equation by substituting "m" since the variable represents minutes, and the submarine has been traveling for 6 minutes.

f(6) = -120 + 13(6)

f(6) = -120 + 78

f(6) = -42

When solved,  the answer is 42.
