Given:
Scale factor is [tex]\dfrac{1}{144}[/tex].
Length of wingspan of the airplane = 1152 inches
To find:
The length of wingspan of the model airplane.
Solution:
Scale factor is [tex]\dfrac{1}{144}[/tex]. It means,
1 inches of airplane [tex]=\dfrac{1}{144}[/tex] inches of model airplane.
1152 inches of airplane [tex]=1152\times \dfrac{1}{144}[/tex] inches of model airplane
[tex]=8[/tex] inches of model airplane
Therefore, the length of wingspan of the model airplane is 8 inches.
