Ship A is traveling west toward a light house at 15 km/hr. Ship B is traveling north away from lighthouse at 10km/hr. x is distnace between ship A and lighthouse at time t, and y is distance between ship B and lighthouse at time t.

Let theta be the angle with the vertex of ship A. find the rate of change of theta in radians per hour, when x=4km and y=3km.


THANKS!!!
