I'd really appreciate some help with this problem: Ally is running around a circular one mile track, her velocity is a constant 6 miles per hours. Barbara is standing at a point 2 miles from the center of the track. Let O be the angle formed from Barbara to the center of the track then to Ally. How fast is the disxtance from David to Susan changing when O = pi/3
