Question

A model airplane is built to a scale of 1 in.:12 ft. If the model plane is 11 inches long, find the length of the actual plane, rounded to the nearest foot.

Answer 1

Answer:

132 feet

Step-by-step explanation:

we know that

The scale is equal to $\frac{1}{12}\ \frac{in}{ft}$

That means ---> 1 inch in the model represent 12 feet in the actual

To find the actual dimensions of the airplane, divide the dimensions of the model by the scale

so

$11\ in:\frac{1}{12}\ \frac{in}{ft}=11(12)=132\ ft$
