I have a problem with distanceTo

I am using a market with another market and I want to know the distance of both because supposedly this one returns it in meters ... but when printing it tells me that it has 13000 of equal distance if it is winged or if it is further away

    if (usuarioposicion.distanceTo(markerLocation1) < 15000){
        BusesMood = 1;
        Toast toast1 = Toast.makeText(getApplicationContext(), "No se encontro Bus que te lleve" + usuarioposicion.distanceTo(markerLocation1), Toast.LENGTH_LONG);
        toast1.setGravity(Gravity.CENTER, Gravity.CENTER_HORIZONTAL, Gravity.CENTER_VERTICAL);

        toast1.show();

}
