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 some time, the angle of elevation reduces to `30^(@)` (see the given figure). FInd the distance travelled by the balloon during the interval.

An observer spots a balloon moving with the wind in a horizontal line at a height of 105 m from the ground. The angle of elevation of the balloon after sometime reduces from 60% to 30%. Find the distance travelled by the balloon during the interval.
