Imagine that there is a circular track given by the equation x2+y2=1123600, where both x and y are measured in units of feet. At time t=0, Robin is at point (1060,0) and Shannon is at point (560,900). Both are running counterclockwise, with Shannon running at 3.9 feet per second and Robin running at 6 feet per second.Robin runs until he catches Shannon. How long does that take? At what point do Robin and Shannon meet?
