Final answer:
The length of the actual plane is approximately 132 feet.
Step-by-step explanation:
To find the length of the actual plane, we can set up a proportion using the scale of the model. The scale is 1 inch: 12 feet, which means that for every inch on the model, there are 12 feet in reality.
Let's set up the proportion:
1 inch / 12 feet = 11 inches / x
Cross multiplying, we get:
x = 12 feet * 11 inches / 1 inch
Simplifying, the length of the actual plane is approximately 132 feet, rounded to the nearest foot.
