A straight 15 meter ladder is left leaning against a wall (which forms a right angle with the ground), touching the wall at a height of 14 meters. The ladder then begins sliding down the wall at a constant rate of 10 centimeters a second. When the ladder is 9 meters from the ground, how fast is the distance between the base of the ladder and the base of the wall increasing (supposing the base slides across flat ground).
