last thing i promise ok the length of the wing of a model airplane is 3 in. if th escale of the model to the actual plane is 1in=25ft wha tis the length of the actual wing? is it 8.3 or 0.12
Neither of those.
Think about it if the model wing is 3 inches long, the actual wing must be much longer than 25 feet.
is it 0.12 can u help me
Use this proportion:
1/25 = 3/x
so its 0.12 right can you u just go thorough it with steps
Cross multiply and solve for x.
so is it 75
Yay! You've got it! :-)
