Question

3. The scale of a model car is 1:32.

Answer 1

Answer: Third option.

Step-by-step explanation:

Let be "x" the approximate actual  width of the car (in feet).

According to the information provided in the exercise, you know that the scale of the model car is:

$1:32$

By definition, this can be written as a fraction:

$\frac{1}{32}$

Therefore, if you know that the width of the model car is 2.3 inches, you can set up the following proportion:

$\frac{1}{32}=\frac{2.3}{x}$

Finally, you must solve for "x" in order to find its value.

This is:

$(x)(\frac{1}{32})=2.3\\\\x=(2.3)(32)\\\\x=73.6$
