# A 1.2 m tall girl

From this figure:

BF = height of girl = 1.2 m,

AG = height of balloon from ground initially = 88.2 m,

AC = AG – GC

= 88.2 – 1.2

= 87 m

∠EBD = 30° and ∠ABC = 60°,

CD = ?

In Δ ABC;

where p = perpendicular and b is base

In Δ ABC,

Now, the distance covered by the balloon will be:

CD = BD – BC

CD = 58√3 m
