Answer:
6 7/8 inches
Step-by-step explanation:
The first thing to do is to get the measurements in either inches or feet. You can't have both. Let's go from feet to inches.
3 feet = 36 inches
13.75 feet = 165 inches
Now we can set up a proportion to solve for the number of inches the model is:
[tex]\frac{model}{real}:\frac{1.5}{36} =\frac{x}{165}[/tex]
Now we can cross multiply:
36x = 247.5 so
x = 6.875 or 6 7/8 inches
