Answer: 195 inches.
Step-by-step explanation:
Given: Sam is building a model of an antique car.
The scale of his model to the actual car is 1:10.
⇒Scale factor = [tex]\dfrac1{10}[/tex]
Since, Length of actual figure = (Length of model ) ÷ Scale factor.
If length of model of car = 19.5 inches.
Then, the length of the actual car = [tex]19.5\div\dfrac{1}{10}=19.5\times10=195\text{ inches}[/tex]
Hence, the length of the actual car = 195 inches.
