Yep, you don't have to mess with those pesky reflections when the
line
is terminated in a load equal to its characteristic impedance. Then
the
problem reduces to the trivial one you've posed. Simple problem,
simple
solution.
=======================================

As I say, I've lost the original question.

But if a steady-state answer is needed for the original question then
the answer can be found by the same simple means without the
unnecessary complication of reflections.

It's the Devil which makes Cecil pose such loaded questions.
