The question is like that.(adsbygoogle = window.adsbygoogle || []).push({});

Q: A ship B is steaming on a straight course south-east at a uniform speed of 15km/h. Another ship A, is a distance of 10 km due north of B and steams at a speed of 12km/h. Find the course that A must steer in order to gets as close to B as possible, and their minimum distance apart.

I want to ask that is that if I find out the relative motion of ship A relative to ship B, will it be helpful to my work? And, if it does, how can I find out the correct course.

Another question is that, does the 10km distance affect the calculation of the relative velocity?

Thx for help
