Sammie sees a cat 120 ft to her east. She then runs to the east at a speed of 12 ft/s. If the cat walks northward at 4 ft/s, how fast does the distance between them change after 8 seconds? (Is the distance increasing or decreasing.) Use calculus concepts in solving this problem about rates of change.
