Question

a maps scale is 1 inch : 2.4 miles. the map shows an airport that is 5 inches away from a city. how far is the actual distance between the airport and the city? ? miles

Explanation:

Step1: Identify the scale ratio

The scale is 1 inch : 2.4 miles, meaning 1 inch on map represents 2.4 miles in real - life.

Step2: Set up the proportion

Let $d$ be the actual distance. We have the proportion $\frac{1}{2.4}=\frac{5}{d}$.

Step3: Cross - multiply and solve

Cross - multiplying gives $1\times d = 2.4\times5$. So $d = 12$.

Answer:

12
