The model's dimensions are always 1/5 the corresponding dimension of the real plane. In this case, the model's length will be 1/5 the length of the real plane or 65*1/5=13 feet.
The length of the scale model of jet plane, which Mags got from online auction is 13 foot.
What is scale factor?
Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
It is given that the, Mags got a scale model of jet plane from an online auction. This model' s scale is 1 foot to 5 feet.
Thus, the scale factor of the model to the original jet plane is given as,
[tex]r=\dfrac{1}{5}[/tex]
Now, Mags looked up the real length and found it to be 65 feet. Suppose the model is h foot long. Thus, scale factor between these two is given as,
[tex]r=\dfrac{h}{65}[/tex]
As both the equation is for the same situation. Thus, compare both the scale factor as,
[tex]\dfrac{h}{65}=\dfrac{1}{5}\\h=\dfrac{65\times1}{5}\\h=13\rm ft[/tex]
Thus, the length of the scale model of jet plane, which Mags got from online auction is 13 foot.
