Answer: If the model kit for the Dornier Do17 airplane has a wingspan of 10 inches and the scale of the kit is 1 inch to 72 inches. This means that for every inch on the model, the equivalent measurement on the actual Dornier Do17 airplane is 72 inches.
We know that the wingspan of the model is 10 inches and we want to find the actual wingspan of the airplane so we'll use the scale factor of 1:72
To find the actual wingspan, we'll multiply the wingspan of the model by the scale factor.
10 inches * 72 inches/1 inch = 720 inches
Therefore, the actual wingspan of the Dornier Do17 airplane is 720 inches or 60 feet.
