If a ship travels at warp 9.5 (TNG era) and encounters no resistance/gravitational affects change the ships velocity and assuming infinite fuel is available, how far does it travel in 123 days?

Frame of reference:

In the episode "Remember Me" of TNG's 4th season, Dr Crusher is stuck inside an experimental warp bubble by Wesley.

After the rest of the crew disappears she decides to try to get to Tau Alpha C from where she is, she asks the computer how long it would take at warp 9.5 to reach there. The computer responds that it would take 123 days. Synopsis
