You are incorrect.

The speed of light is constant within the inertial system. I am saying that when we change the inertial system we get different solutions for the speed of light. "The principle of inertia and the principle of the velocity of light are valid only with respect to an inertial system." Einstein - revised edition of Relativity, The Special And The General Theory: A Popular Exposition.

In each example I described the time remains contant for the observer. The distance changes though because we are comparing it to different objects with different motions. The distance increases for each example and the time remains the same. The math would look like x/t, (x+y)/t, (x+y+z)/t and so on.
