A student in a noon calculus class is watching two bugs near the center of a wall. One is an ant and the other is a beetle. At noon, the ant is 180 cm directly to the left of the beetle. The ant is crawling right at 30 cm/h and the beetle is crawling up at 45 cm/h. How fast is the distance between the bugs changing at 2:00 PM? Answer with an exact value. cm/h?
