To measure real-world distances using maps, it's important to understand how to read ratio scales.
A ratio scale shows the relationship between a distance on the map and the actual distance on the ground. It uses a simple number comparison.
For example, if a map has a scale of 1:50,000, that means 1 unit on the map (like 1 centimeter) is equal to 50,000 of the same units in real life (which is 50,000 centimeters or 500 meters).
Find the Scale: Look for the ratio scale on the map.
Use a Ruler: Measure the space between two points on the map with a ruler.
Calculate Real Distance: Multiply the distance you measured by the scale number.
If the scale is 1:50,000 and you measured 3 cm, the real-world distance is calculated like this:
Real Distance = Measured Distance × Scale Factor
Real Distance = 3 cm × 50,000 = 150,000 cm = 1,500 meters
Using ratio scales helps us understand distances better. This is really important for navigating and studying places.
