--A canoeist wants to get to a campsite that is on a bearing of
330° and at a distance of 2 km across a lake. The canoeist can
paddle at 5 km/h in still water. The lake current is 1 km/h on a
bearing of 020°. The wind is blowing due north at 3 km/h. The
combined effect of the current and the wind is called the
off-course vector. Find the off-course vector
