Find the distance of the board of the ship. 14. A 1.2 m tall girl sees a balloon flying in a horizontal line at a height of 88.2 m from the ground. At any moment the angle of elevation of the balloon from the girl's eye is 60 °. After some time the angle of elevation decreases to 30 ° (see figure 9.13). Find the distance traveled by the balloon during this interval. 88.2m 600 B000 Figure 9.13
