A 1.2m tall girl spots a balloon moving with the wind in a horizontal line at a 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 sometimes, the angle of elevation reduces to `30^(@)`. Find the distance travalled by the balloon during the interval.
