a marine biologist is studying a pod of dolphins. The dolphins are swimming in the Gulf Stream and several were tagged with GPS tracking devices. The marine biologist is in a boat, motoring parallel to the pod with a speed of 6 m/s at 60 degrees south of west (or would be, if there was no current.) According to a NOAA buoy anchored nearby, the current is 1 m/s at 35 degrees east or north. How fast and in what direction should the pod be swimming according to the GPS?
