A boy is observing a hot air balloon flying at 692 m above ground. The angle of elevation of balloon from the eyes of the boy was 60°. After sometime, the balloon moves away horizontally from the boy and the angle reduces to 30°. What is the approximate distance travelled by the balloon? Take \(\sqrt 3 = 1.73\)
