A \(1.2 m\) tall girl spots a balloon moving with the wind in a horizontal line at a height of \(88.2 m\) from the ground. The height of \(88.2 m\) from the ground. The angle of elevation of the balloon from the eyes of the girl at any instant is \(60^°\). After some time, the angle of elevation reduces to \(30^°\) (see Fig.). Find the distance traveled by the balloon during the interval.
