The distance on the map between Yappy City and Quiet city is 23 cm. What is the actual distance between the cities? (5 cm : 2 miles)

You can write the conversion factor as an equation.

... 5 cm (map) = 2 miles

Now, you can multiply this equation by 23/5.

... (23/5) * 5 cm (map) = (23/5) * 2 miles

... 23 cm (map) = 9.2 miles

The actual distance is 9.2 miles.
