My friend and I start on opposite ends of a circular track. At the same time we start running in the same direction. I run at a constant pace of a lap every two minutes around the outside of the track (63 meters from the center) and my friend runs at a constant pace of a lap every three minutes around the inside of the track (61 meters from the center). When the angle formed by lines from my friend and myself to the center is at 7 and I am behind my friend, how fast is the distance between us decreasing? What if I were in front of my friend, how fast is the distance between us increasing?
