title: How to move a marker 100 meters with coordinates
body: <p>I have 2 coordinates. Coordinate 1 is a 'person'. Coordinate 2 is a destination.</p>
  <p>How do I move coordinate 1 100 meters closer to coordinate 2?</p>
  <p>This would be used in a cron job, so only php and mysql included.</p>
  <p>For example:</p>
  <blockquote>
  <p>Person is at: 51.26667, 3.45417</p>
  <p>Destination is: 51.575001, 4.83889</p>

  <p>How would i calculate the new coordinates for Person to be 100 meters closer?</p>
