Maybe it's not so far? In this context it's a question, but it could also be used as a statement.
It would be "Kanskje er det ikke så langt?" as the verb would need to be in second position so "det" and "kanskje" just swap positions.
Are these also correct? 1. Kanskje det er ikke så langt 2. Det er ikke så langt Kanskje And which is more common?
