Answer: The scale factor tells us the ratio of the size of the model to the size of the actual object. In this case, the scale factor is 5:8, so the model is 5/8 the size of the actual object.
If we know that the actual width is 20 ft and we want to find the width of the model, we can set up an equation using the scale factor:
(Model width) / (Actual width) = 5/8
Cross-multiplying and solving for the model width, we get:
Model width = (Actual width) * (5/8) = 20 ft * (5/8) = 25/4 ft = 6.25 ft
So, the model width is 6.25 ft.
