title: get distance between two places
body: <p>I actually am trying to find the distance between two places, I am new to this. I came to know about openstreetmap. But I am not sure what to do. </p>
  
  <p>I found a traveling salesman application that uses osm to route. 
  But here my question is how to get a osm between places .e.g. "<a href="http://www.openstreetmap.org/api/0.6/map?bbox=10,30,10,30" rel="nofollow">http://www.openstreetmap.org/api/0.6/map?bbox=10,30,10,30</a>" this gives me the map of the box (10,30,10,30) .. but if I want to get the map between leeds and sheffield what should be my query.</p>
  
  <p>Or is there any other way to find the distance.(As I am a student I want some open source way for my academic project..)</p>
  
  <p>please suggest..</p>
