A ship B is travelling due West at 25.6 km/hr. A second ship C travelling at 32 km/hr is first sighted 17 km due North of B. From B the ship C appears to be moving towards South-east. Let g, c and CB be the velocity of ship B, velocity of ship C and the velocity of ship C relative to ship B respectively. The directions of og and CB are shown in the figure below. 17 km VCB SE (a) Find the direction in which C is actually moving. (b) Find the speed of C relative to B. (c) Find the shortest distance between the ships in the subsequent motion. (d) Find the time that elapses, after first sighting, before the ships are again 17 km apart.
