Thom has a scale model of his car. The scale is 1 inch = 12 inches. If the actual car has 16- inch wheels what size are the wheels on the scale model.
I don't know where to begin
Use a proportion. Cross multiply and solve for x.
1/12 = x/16
12x = 16
x = 16/12 = 1 1/4 inches
To determine the size of the wheels on the scale model, you first need to understand the scale ratio given. The scale ratio tells you how the size of the actual object relates to the size of the model object.
In this case, the scale is given as 1 inch = 12 inches. This means that every inch on the scale model represents 12 inches on the actual car. Now, let's apply this to the wheel size.
Since the actual car has 16-inch wheels, we need to find out how many inches those wheels will be on the scale model. To do this, we need to calculate the ratio of the actual wheel size to the scale ratio.
The calculation will be as follows:
Actual wheel size / Scale ratio
Substituting the values:
16 inches / 1 inch = 16 inches
Therefore, the wheels on the scale model will also be 16 inches.
