Man got stuck working with Google matric Api to determine distance, duration of travel etc from two points on the map. values the api spat out was a jumple of hash values that took me a while to understand how to traverse it.


matrix = 
{
  "destination_addresses":["Egypt Rd, Accra, Ghana"],
  "origin_addresses":["8 Third Dade Walk, Accra, Ghana"],
  "rows":
  [
    {"elements":
      [
        {
          "distance":
          {
            "text":"5.0 km",
            "value":5047
            },
          "duration":
          {
            "text":"12 mins",
            "value":734
            },
            "status": "OK"
            }
              ]
               }
              ],
              "status":"OK"
              }

Ever wondered how to traverse an array/hash like this? code snippet below will output : "5.0km"

matrix[:rows][0][:elements][0][:distance][:text]

Think on it !!
