Jim is building a model airplane the scale is 2 inches to 40 inches the actual week wingspan of the plane is 220 feet how long will the wingspan of the model B

The wingspan of the model will be 11 feet long

Step-by-step explanation:

Here, we want to find the length of the wingspan of the model.

From the question, the scale we have is; 2 inches to 40 inches

So let’s say the ratio of the model length to the actual length is 2:40 = 1:20

Now , we have an actual length but we do not know the model length. Let the model length we are looking for be x;

Thus;

1/20 = x/220

Cross multiply;

20 * x = 220 * 1

20x = 220

x = 220/20

x = 11 feet

Kindly note that since we are working with ratio here, we do not need any unit conversion from feet to inches or vice versa

x/3-10=8

x/3=18

x=48
