Question

On a map, if one centimeter represents 25 kilometers, how many kilometers does 7 centimeters represent?

Answer 1

x = 175 km

Explanation:

We can use ratios to solve this problem. Put the map distance over the real life distance.

25 km x km

Using cross products.

1 * x = 7 * 25

x = 175 km
