Answer:
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
