Solution:
we are given that
Airplane has a wingspan of 15 feet.
we have been asked to find the wingspan of a model of the airplane, in inches, if the scale factor is 1:60 .
It mean for each one unit of original wingspan we are supposed to have [tex]\frac{1}{60}th[/tex] times the wingspan of model airplane.
Here the original airplane has a wingspan of 15 feet. So the model airplane has a wingspan of [tex]\frac{1}{60}*15=\frac{1}{4} ft[/tex]
Since one fit=12 inches So we can say
[tex] \frac{1}{4} ft=\frac{12}{4} inches=3 inches.[/tex]
Hence the model airplane has a wingspan of 3 inches.
