The submarine is at a depth of -116 2/7 feet when the scientists detect a signal frequency from the ocean floor. They dive farther down to a depth of -180 4/7 feet to check the signal. The net change in their elevation is what feet?

-116 2/7 - X = -180 4/7
Where -X= -180 4/7 +116 2/7
And finally: X= -64 2/7
