Final Question!!! A model car is created using a scale of 1:12. The model has a length of 24 inches. What would the length of the model be if it were created using a scale of 1:8? |
|

If the scale was 1:12 and the model was 24 inches or 2 feet, the real car would be 24 feet long. If the real car was 24 feet long and a scale of 1:8 was used to make a model, the model would be 3 feet long because 1 = x 8 24 8x = 24, so x = 3 |
