2. How long it would take for the incoming particle to travel these two distances?

Hopefully the attached picture help to explain these questions clearly...

In an attempt to help the original poster find some clarity, I believe the answer is different depending on where you observe the particle from. Perhaps a little elaboration might help focus the brains trust? :-)
