      Is he due north of the starting point, or of the girl? If the former, he is traveling due north. If the latter, his 5ft/sec velocity has a 1ft/sec eastward component, and we need to calculate the northern component.

      Wait, we know their position exactly? That means we have no idea what their velocities are!

      Actually, their velocities are specified precisely in the problem description.

      What? Velocity too? Now we know nothing!!
