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.
