To find the real length of the wing on the airplane, we can use the scale of the model. In Bill's model, \( \frac{1}{4} \) inch represents 1 foot.
If the model airplane has a wing that is 4 inches long, we can convert this measurement into feet using the scale.
-
First, we determine how many \( \frac{1}{4} \) inch segments are in 4 inches:
\[ 4 \text{ inches} \div \frac{1}{4} \text{ inch} = 4 \times 4 = 16 \]
-
Since each \( \frac{1}{4} \) inch segment represents 1 foot, the real wing length is:
\[ 16 \text{ feet} \]
Thus, the wing on the real airplane is 16 feet long.
