The question is this:
A yacht is travelling due WEST at 6km/h. 3km NORTH WEST of the boats location, there is a boat travelling 4km/h, SOUTH WEST. How close to eachother do the boats get.
From how I understand these questions, I needed to sub something into a distance forumla (distance between 2 coordinates)... I could sub in some form of general coordinates for each boat's path.... or I could sub in their position equations....
I don't know how to begin this question!!! I'm drowning in this stuff..
