If you start from A1 you have to add 1 in order to calculate the total
time
v/(c-v) + 1 = v/(c-v) + (c-v)/(c-v) = (v + c - v)/(c-v) = c/(c-v)
And that is your answer,
which is correct

And so is my answer.

Yes, but be aware of the fact that your statement
| 1. When the clock of A reaches 1 time unit (t=1), A issues a light
| sinal to B.
explicitly means that you start with [A0], not with [A1].


Your method is more general

I wouldn't say more general.
It's just standard basic 2D analytic geometry.
And so is your method. We just take different origins.

I fully agree.
All problems solved
And they lived happily thereafter.
Unfortunate it is not tea time anymore but coffee time

And I have still to answer Paul B Andersen.
