unit hyperbola and circle

Please see attachment. That there is a unit circle. The hyperbola is also unit. This is all the information you need. Yes, I threw in an ellipse too.

I.

Find the y coordinate of the point where the two red lines intersect.

Find the y axis intercept of the purple line.

II.

If the two blue lines are railroad tracks receding into the distance and meeting at the totally flat horizon line (light green), and an ant observer is standing on the x axis, what is the real distance from the ant of the two y values found in part I?
