A small ship of marine biologists in search of a large pod of whales is anchored 5 miles north and 9 miles east of a location where the pod was recently observed

3-mile radius. If the whales are currently 7 miles due south of their former hunting
location and traveling directly northeast, where will the whales first be within the
detection range of the researchers?
