scale model?
A. 1.3 in
B. 2 in
C. 3 in
D. 4 in
16.10.

Answer 1

By applying the scale factor of 1:12 to the actual 16-inch wheels, we find that the wheels on the scale model would be approximately 1.3 inches in size, corresponding to option A.

Step-by-step explanation:

The student asked: If Thom has a scale model of his car with a scale factor of 1:12 and the actual car has 16-inch wheels, what size are the wheels on the scale model?

To calculate the size of the wheels on the scale model, we apply the scale factor to the actual size of the wheels. Since the scale factor is 1:12, each unit on the model represents 12 units on the actual car. Therefore, we divide the actual wheel size by the scale factor as follows:

Actual wheel size: 16 inches

Scale factor: 1:12

Model wheel size: 16 inches / 12 = 1.333 inches

The size of the wheels on the scale model would be approximately 1.3 inches, which corresponds to option A.
