A 15-foot ladder is leaning against a vertical wall when Josiah begins pulling the foot of the ladder away from the wall at a rate of 0.4 ft/s. How fast is the top of the ladder sliding down the wall when the foot of the ladder is 7 ft from the wall? (Your solution must include correct units, equations, and derivatives.)
