A tired hiker is asking how much further they have to walk to reach the campsite. Select ALL the encouraging replies that use perfect grammar for describing distance.
The correct answers are Keep going, it is only one mile away! and It's a very short walk from here.
When we talk about distance, we use it as an empty or "dummy" subject.
"Is not far" is incorrect because it is missing a subject, and "The camp it is" incorrectly uses two subjects for the same verb.
