how can we access distance field?

[H. Can Yıldırım]

Hi, I want to show the distance between the locations that exist in the database of latitude and longitude values I sent to the query. How can we access this distance information?

example:

@locations = Location.within(5, :origin => @somewhere)

distance value should be calculated by @somewhere coordinates and returns like below:

{
  "data": [
    {
      "name": "Paris",
      "distance": "200 meters"
    },
    {
      "name": "New York",
      "distance": "2000 meters" 
    }
  ]
}
