- Example 1: A 26-foot ladder is placed against a wall. If the bottom of the ladder is moving away from the wall at 3 feet per second, at what rate is the top moving down when the top of the ladder is 24 feet above ground? - Example 2: Suppose that two motorboats leave from the same point at the same time. If one travels north at 15 miles per hour and the other travels east at 20 miles per hour, how fast will the distance between them be changing after 3 hours - Example 3: A point is moving on the graph of \( y^{3}=x^{2} \). When the point is at \( (-8,4) \), its \( y \) coordinate is decreasing by 2 units per second. How fast is the \( x \) coordinate changing at that moment?
