Chris's uncle has a model car. The model is 6 inches long and 3 inches wide. The actual car is 75 inches long. What is the cars actual width, if we assume the models proportions are accurate? If necessary, round to the nearest tenth of an inch. A. 25 inches B. 37.5 inches C. 150 inches D. 225 inches
Accepted Solution
A:
The model car has a length to width ratio of 6 : 3
therefore the actual car should also have similar ratio. Let us say that x is
the width of the actual car, hence:
6 : 3 = 75 : x
6 / 3 = 75 / x
Calculating for x:
x = 75 * 3 / 6
x = 37.5 inches
