Tony, really, this is village idiot level.
a + b
_________
ab
1 + ____
c^2
When a and b are c, the combined velocities are c.
Another way to look at it is to say that the photons experience no elapsed
time from emission to absorption, hence the distance they cross is
effectively zero.
Is this so hard to grasp?
