1. It is 10km away from this island to that island.

2. It is 10km from this island to that island.
----------------------------
Are both okay? Do we have to use 'away' or not? Is 'It' refers to 'the distance'?

Second one makes sense, first does not. I think it is better to use "the distance" instead of "it" as "it" is indefinite.

I disagree with Brea to an extent. "It" does refer to the distance and is perfectly acceptable. She's right that #2 is better than #1. Using "away" is redundant, although not incorrect. It's just an extra word.

Thank you for your help.

3. This island is 10km away from that island.

4. This island is 10km from that island.
[What about #3 and #4? Which one is right in these sentences?]

I agree with Reed that #2 is much better than #1.

Both #3 and #4 work fine. I prefer #3, but they mean the same thing.

Both sentences #3 and #4 are grammatically correct and convey the same meaning. The word "away" in sentence #3 is optional and can be omitted without changing the meaning of the sentence. Therefore, both sentences are equally acceptable and it comes down to personal preference whether to include or exclude the word "away."
