Hope that helps.

[update] Here are the formulas in JavaScript (copied from source)

var lat2 = Math.asin( Math.sin(lat1)*Math.cos(d/R) +                       Math.cos(lat1)*Math.sin(d/R)*Math.cos(brng) ); var lon2 = lon1 + Math.atan2(Math.sin(brng)*Math.sin(d/R)*Math.cos(lat1),                              Math.cos(d/R)-Math.sin(lat1)*Math.sin(lat2));

d=distance traveled=velocity x time R=radius of the earth
