At the entrance channel of a harbor, the tidal current has a velocity of 4.34 km/hr in a direction 24.1o south of east. Suppose a ship caught in this current has a speed of 17.9 km/hr relative to the water. If the helmsman keeps the bow of the ship aimed north, what will be the speed of the ship relative to the ground?
