$distance is an integer? why don't you just write
var dist = <?php echo $distance; ?>
If the value in $distance is just an integer, you don't need the json_encode call. You can just do a php echo of $distance.
Something like
var dist = <?php echo $distance; ?>;

if you right click > view html source in your web browser, you would see for yourself that you have an extra set of quotes.
And, good for you for using json_encode() to output it as a string. That's an excellent way to safely output a value to javascript. although, if its an integer, theres no need here.
