We have a circle radius=25 miles, with center at origin.
Traveller A is on circle's circumference, at A(20,15).
Traveller B is on x axis, at B(39,0).
They leave at same time, A travelling along the circumference counter clockwise,
B travelling in a straight line, such that A and B arrive at point P(u,v) on the
circle's circumference at same time.
if the speeds of A and B are given, what is "easiest" way to calculate u and v?
Say the speeds are A = a mph, B = b mph.
