Question

Sam is building a model of an antique car. The scale of his model to the actual car is 1:10. His model is 19.5 inches long. How long is the actual car?

Answer 1

Answer: 195 inches.

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 =
`\frac1{10}`

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 =
`19.5/(1)/(10)=19.5*10=195\text{ inches}`

Hence, the length of the actual car = 195 inches.
