Answer:
The distance travelled by the kite is 122.8 ft ( approx )
Step-by-step explanation:
Here, the given function,

Differentiating with respect to x,

∵ arc length of a curve is,

Where, y shows the height of the curve for a ≤ x ≤ b,
Thus, the arc length of the given curve is,
Put 




By integration by parts,

If x = 80, 



Thus, the length of the curve is,
