Meeting point

There are 2 particles moving on the unit circle (x^2+y^2=R^2 and R=1). Particle A moves clockwise at a speed equal to 2+x while particle B moves counter-clockwise at a speed equal to 2+x, where x and y are the coordinate values of the moving particle. At T=0 time; A is located at (-1,0) and B at (0,-1), so the speeds would be 1 and 2 for A and B respectively. Where do they first meet and when? Answer format: X,Y,elapsed time X,Y rounded to 3 digits after decimal point elapsed time is a decimal number (rounded to 12 digits after decimal point)
