One end of a ladder 34 feet long slides down a vertical wall while the other end moves away from the wall horizontally at a rate of 4 feet per second. How fast is the top of the ladder descending when its foot is 16 feet from the wall? Write the answer in its exact form as an integer or a fraction in lowest terms. The top of the ladder is descending by Blank 1 feet per second, at an instant.
