Hello - I am writing a puzzle about Russian spies in New York and am having some difficulty figuring out the correct plural term in Russian to use for "distances".

Right now I am using расстояний

But most of the online dictionaries I find are translating this as "distance".

When I lop off the last character, making the word расстояни

The online dictionaries then translate it as "distances".

This is counter-intuitive to me, and I was wondering if I was doing anything wrong...

Is расстояний the plural term, translating to "distances", or have I gotten myself horribly confused?

Thank you very much!
