Answer:
The answer is 27 mi; 42 mi
Explanation:
The scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.
On the other side, in the image you can see too that the distance from New Wilmington to Mercer is 1 in and the distance from Mercer to Sharon is also 1.25 in. So to calculate the distance from New Wilmington to Sharon through Mercer you must add the distance New Wilmington to Mercer and from Mercer to Sharon: 1 in + 1.25 in = 2.25 in. Since the scale is 1 in: 12 mi, then you can apply a simple rule of three:
If 1 in of the drawing represents 12 mi in real dimensions, what is the real dimension of 2.25 in?

⇒ 27 mi
On the other side, in the image you can see too that the distance from New Wilmington to Volant is 1.75 in and the distance from Volant to Sharon is also 1.75 in. So to calculate the distance from New Wilmington to Sharon through Volant you must add the distance New Wilmington to Volant and from Volant to Sharon: 1.75 in + 1.75 in = 3.5 in. Since the scale is 1 in: 12 mi, then you can apply a simple rule of three:
If 1 in of the drawing represents 12 mi in real dimensions, what is the real dimension of 3.5 in?

⇒ 42 mi
