Let be "x" the approximate actual width (in feet) of the car.
Based on the information provided in the exercise, you know that the scale of the model car is this one:
Which can be written as a fraction:
Therefore, if you know that the width of the model car is 2.3 inches, you can set up the following proportion:
Finally, you must solve for "x" in order to find its value.
So you get the following result:
