I am confused with setting a course in relative motion.
Please could you tell me, step by step, and if possible with a diagram, how you would go about solving this question:
A ship P is moving on a bearing of 055 degrees with speed 18km/h. A second ship Q is initially 6 km from P on a bearing of 155 degrees, and moves with speed 15km/h.
Find the course Q must set in order to pass as close to P as possible
What should I do?
