Question

9) A model airplane kit has a scale factor of 1/144. If the wingspan of the airplane is 1152 inches long, how long would the wingspan of the model airplane be? (Type just the number without the units)

Answer 1

Given:

Scale factor is $\dfrac{1}{144}$.

Length of wingspan of the airplane = 1152 inches

To find:

The length of wingspan of the model airplane.

Solution:

Scale factor is $\dfrac{1}{144}$. It means,

1 inches of airplane $=\dfrac{1}{144}$ inches of model airplane.

1152 inches of airplane $=1152\times \dfrac{1}{144}$ inches of model airplane

                                       $=8$ inches of model airplane

Therefore, the length of wingspan of the model airplane is 8 inches.
