Question

A company creates model cars using a 1.5 ft:1 inch ratio when creating models. If a real car is 12 ft long, how long will the model car be?

Answer 1

Length of model car is $8ft$ .

Step-by-step explanation:

Here we have , A company creates model cars using a 1.5 ft:1 inch ratio when creating models. If a real car is 12 ft long , We need to find that how long will the model car be . Let's find out:

For model cars the ratio is $1.5:1$ as $length:breadth$ , And it's given that real car is about 12 ft long that means

⇒ $1.5(Length)= 12$

Where Length = length of model car

⇒ $1.5(Length)= 12$

⇒ $\frac{1.5(Length)}{1.5}= \frac{12}{1.5}$

⇒ $Length= \frac{12}{1.5}$

⇒ $Length= \frac{8(1.5)}{1.5}$

⇒ $Length=8ft$

Therefore, Length of model car is $8ft$ .

Answer 2

8 inches

Step-by-step explanation:

Step 1:

For 1.5 ft it is equal to 1 inch

For 12 feet it will be equal to

Step 2:

1.5:1 :: 12 : x

By using expansion method,

1.5 x = 12

x = 12/1.5 = 8
