Acording to this map:

And the fact that Tieflins tells us that "it takes around 3 days to get into Baldur's Gate" ...

I just noticed that there is scale in down left corner ... i really should zoom out.

Since Tieflins are traveling with (or more likely at) Waggons ... i shall presume they should be able to travel 100 miles in 3 days ...
That would mean that on big map we are +/- here:
