Study the road plan shown in the figure. A service station will be built on the highway, and a road will connect it with Cray. H
1 answer:
The length of the road that connects the service station with Cray is 46.2 mi.
<h3> How long will the new road be?</h3>
We need to apply the principle of similar triangles to obtain the length of the road that will connect the service station with Cray as shown in the image attached.
Hence;
The distance between Alba and Blare = 130 mi
The distance between Alba and Cray = 120 mi
Road connecting the service station with Cray =x
And;
120/130 = x/50
x = 46.2 mi
