Question

If you are given a distance in Nautical mile and you have initial Lat Long how can you calculate next lat long?

i have initial lat 30.2735 and initial long 68.4455 now i want to calculate the next lat long which should be at a distance of 30 NM. How can i calculate this any formula for this problem ?

You should also provide moving direction (bearing, azimuth). Then you can apply formula from Destination point ... section

JavaScript:
(all angles 
in radians)
var φ2 = Math.asin( Math.sin(φ1)*Math.cos(d/R) +
                    Math.cos(φ1)*Math.sin(d/R)*Math.cos(brng) );
var λ2 = λ1 + Math.atan2(Math.sin(brng)*Math.sin(d/R)*Math.cos(φ1),
                         Math.cos(d/R)-Math.sin(φ1)*Math.sin(φ2));
