Rather than talk in terms of three dimensional density lets talk in percentage of the length of solid matter L_{s} (red
line below left) in a straight line of length L_{t} (purple line below left) The solid percent (S%) is: 
If the travel of impulse through the 100% matter is instantaneous (t_{s} is infinitely small) and the solid traversed has finite length (L_{s}) then the speed of impulse transmission is v_{s}=L_{s}/t_{s} is infinitely large, The observed speed will appear much greater than the ambient speed of an element of matter in a vacuum. 
t_{s} 0 t_{t} t_{v} L_{t} = L_{s} + L_{v}, or v_{t}t_{t} = v_{s}t_{s} + v_{v}t_{v} 
We have the total length L_{t} . Time t_{s} and speed v_{s} are not clear. As t_{s} approaches zero v_{s} approaches infinity. Momentum is difficult to talk about . Here is a clear difference. Momentum travels in one mass and transfers to another. The mass in not transferred and momentum jumps to the next mass.
