Rock has a Model Truck it has a scale of 1 inch for every 32in on a real size truck he wants to build a garage for the model at the same scale give that the garage for real size truck is 12 feet wide how wide should his Model Garage be

Answer 1

Solution

We need to convert ft to inches first like this:

$12ft\cdot\frac{12in}{1ft}=144in$

For this case we can solve the problem with the following proportion:

$\frac{144in}{32in}=\frac{x}{1in}$

So then the model present the following size:

$x=\frac{144}{32}=4.5in$
