Answer:
~ 8.4 centimeters of the route on map ~
Step-by-step explanation:
Let us plan out our steps, and solve for each:
1. We can see that we have to determine the cm of the route on the map, so let us convert the 2.1 kilometers ⇒ centimeters:
2.1 km = 210,000 cm
2. Given the information, let us create a proportionality as such:
1 = 25,000 ⇒ x - centimeters of the route on the map
x 210,000
3. Now let us cross multiply, and solve through simple algebra for x:
25,000 * x = 210,000,
x = 8.4 centimeters of the route on map
