Two cars start moving from the same point. One travels south at 20 mi/h and the other travels west at 15 mi/h. At what rate (in mi/h) is the distance between the cars increasing four hours later? Step 1 Using the diagram of a right triangle given below, the relation between x, y, and z is 2-? +y² 7 + y² Step 2 We must find dz/dt. Differentiating both sides and simplifying gives us the following. dz dx + 2y = 2x dt dy dt dt dt 1 v (x
