Phoebe is going east on Alamo street at 40 ft./second, meanwhile Calvin is going south on heights street at 30 ft./second. We need to determine the straight line distance between them. Then, when Phoebe is 200 feet from the intersection, Calvin is 600 ft. from the intersection. At this time is the straight-line distance between them increasing or decreasing? At what rate?

Thanks!
