Simply type in the name of the two places in the text boxes and click the show button!
The best format to use is [City, Country] to enter a location - that is [City(comma)(space)Country]. You can also type in major places straight in such as "USA", "Tokyo", "London" etc. Postcodes and addresses can also be used.
When you click the search button, a search will be made to find which place you are referring to. Firstly, a search is made of an internal list of common places. If no match is found then a search will be made using the Google Maps API GlocalSearch feature. If this also returns no results then you are asked to indicate the location of the point by clicking on the map. This allows you to then see the distance between the two points and also inputs the location into the internal database so that the next time a visitor searches for that location, it will be found.
Once a result is returned, you can copy a URL to use as a permanent link back to the result for your own reference or to pass on to other people.
espero te sirva:)
