Suppose the ship is to the north of A and B. Draw a sketch and find out where the ship is located. (b) At the same instant, station A reads that the distance between station A and the ship is increasing at the rate of 28 km/h. Station B reads that the distance between station B and the ship is increasing at 4 km/h. How fast and in what direction is the ship moving?
