Answer:
~ 10 centimeters of the route on the map ~
Explanation:
Let us plan out our steps, and solve for each:
1. If we are to determine the cm of the route, convert 1.5 km ⇒ cm:
1.5 km = 150,000 cm
2. Given the information, let us create a proportionality as such:
1 = 15,000 ⇒ x - centimeters of the route on the map
x 150,000
3. Now let us cross multiply, and solve through simple algebra for x:
15,000 * x = 150,000,
x = 10 centimeters of the route on the map
