Sound is used to measure ocean depth. sound travels 1.5 km per second through water. if it takes 3.7 seconds for a sound to reach the bottom of the ocean how deep is the water

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

the answer for the question that you are asking is 4
