Let t represent the time the stone fell in the air.
distance = speed * time
t*16 + (12-t)*3 = 127 . . . . . total length of travel
13t = 91
t = 7 . . . . . time in air
The stone fell 7 seconds in the air, then 5 seconds in the water.

The correct answer would be A.
We can immediately eliminate C and D because they have the slope listed as 2 rather than -2.
Because we're looking for the line that passes through (1, 5), we know that the y-intercept has to be 7, because from (0, 7) we get to (1, 5) when we apply the slope of -2.
Thus, the answer is A.
