Navigating the World with Math

Maps use scales to show real distances in a smaller, manageable way. Understanding scale helps you calculate actual distances between places.

What is a Scale?

A map scale might say 1 inch = 10 miles. That means every inch you measure on the map equals 10 miles in real life.

• If two cities are 3 inches apart on the map, they're \( 3 \times 10 = 30 \) miles apart.

Using Math in Navigation

• Planning a road trip? Use the map scale to estimate travel distance.
• Reading blueprints or models? Scaling helps builders create accurate plans.
