Answer:
<em>~ </em><em>x = 12 centimeters of the route on map</em><em> ~</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. We can see that we have to determine the cm of the route on the map, so let us convert the 1.8 kilometers ⇒ centimeters:</em>
1.8 km = 180,000 cm
<em>2. Given the information, let us create a proportionality as such:</em>
1 = 15,000 ⇒ x - centimeters of the route on the map
x 180,000
<em>3. Now let us cross multiply, and solve through simple algebra for x:</em>
15,000 * x = 180,000,
x =<em> 12 centimeters of the route on map</em>
