The speed of the moving walkway relative to the airport terminal exists at 1.84 m/s.
<h3>How to estimate the speed of the moving walkway relative to the airport terminal?</h3>Let x be the speed of the walkway.
(2.8 + x) = speed of child moving in direction of the walkway
(2.8 - x) = speed of child moving against the direction of the walkway
Travel time = distance/speed
Travel time of child moving in direction of walkway = 23/(2.8+x)
Total elapsed time given = 29s
23/(2.8 + x)+ 23 / (2.8-x) = 29
LCD = (2.8 + x)(2.8 - x)
simplifying the equation, we get
Speed of walkway = 1.84 m/s

Answer
Find out the what is the value of n.
To prove
By using the parallelogram property .
In parallelogram opposite angels are congruent .
As shown in the figure .
∠B = ∠ D
As given
∠B = (2n + 32)°
∠D = (4n - 2)°
(2n + 32) = (4n - 2)
solving the above
4n -2n = 32 +2
2n = 34
n = 17
Therefore the value of n is 17 .
