How to calculate the average distance ,speed and time on nutiteq while tracking

Question

I am experimenting using nutiteq , as i found it a better alternative working on 3d maps.I want to learn every bit of it.So I am making a simple project where I can calculate the speed distance and time from its current location simultaneously on its tracking. I applied some logics but failed.Can any of you help me.

public final static double AVERAGE_RADIUS_OF_EARTH = 6371;
public int calculateDistance(double userLat, double userLng, double venueLat, double venueLng) {

        double latDistance = Math.toRadians(userLat - venueLat);
        double lngDistance = Math.toRadians(userLng - venueLng);

        double a = (Math.sin(latDistance / 2) * Math.sin(latDistance / 2)) +
                        (Math.cos(Math.toRadians(userLat))) *
                        (Math.cos(Math.toRadians(venueLat))) *
                        (Math.sin(lngDistance / 2)) *
                        (Math.sin(lngDistance / 2));

        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));

        return (int) (Math.round(AVERAGE_RADIUS_OF_EARTH * c));

    }

This is what I have used so far and is calling this function onLocationChange.

Please help. Thanks in advance

This is my code and is working well:

case R.id.btn_StartTrack:

                location_manager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);

                Criteria criteria = new Criteria();
                criteria.setAccuracy(Criteria.ACCURACY_FINE);
                provider = location_manager.getBestProvider(criteria, false);
                //location.getAccuracy();

                if (location_manager.isProviderEnabled(LocationManager.GPS_PROVIDER))
                {

                    if (!isclickedBtnStartTrackFirstTym)
