141304 A balloon is moving up in air vertically above a point \(A\) on the ground(d). When it is at a height \(h_{1}\), a girl standing at a distance \(d\) (point \(B\) ) from \(A\) (see figure) sees it at an angle \(45^{\circ}\) with respect to the vertical. When the balloon climbs up a further height \(h_{2}\), it is seen at an angle \(60^{\circ}\) with respect to the vertical if the girl moves further by a distance \(2.464 \mathrm{~d}\) (point \(\mathrm{C}\) ). Then, the height \(h_{2}\) is
