The scale of the map is 1 centimeter = 15 kilometers, which we can write as the following unit rate.
15 kilometers/1 centimeter
By multiplying this unit rate by 4.6, we get the number of kilometers that corresponds to 4.6 centimeters on the map.
15 kilometers* 4.6/1 centimeter* 4.6=69 kilometers/4.6 centimeters
As we can see, the actual distance is 69 kilometers.
