18cm * 5km/3cm = 6*5 km = 30 km
That is called the "scale" of the map.
it is an indicator used to determine the distance on a paper and the actual distance on the ground.
look at the scale of the map
A graphic scale is one type of map scale, which tells you how distance on the map compares to the actual distance across the land. Graphic scales show the scale as a line or a bar with the distance markings on them. Other types of map scales include numeric (such as 1:24,000 means one inch on the map represents 24,000 inches on land), or verbal (1 inch=1 mile).

the map scale
Map scale is a way of representing actual distance in relation to a map. For example, a distance of 1 inch on the map may be equal to 10 actual miles.
It is the 'scale factor'
A map scale.
if a map show the straight line distance between two cities as 3 and one half centimeters and the map scale show that 1 centimeter equals 100 kilometers what would the actual distance be ?
The scale of a map shows the relationship between the map distance and real world distance. The average scale is one eighty-thousandth of the actual size.
The scale of a map may indicate the ratio as well as showing how lengths measured on the map represent actual distances.
Is the relationship between the distance measured on the map to the actual distance on the ground
That is called the "scale" of the map.
The SCALE of the map indicates the relationship between distances measured on a map and the actual distances.
scale
The term for the relationship between the distance on the map and actual distance is the "scale"For example, the scale may be 1 inch equals 10 miles.So for every inch on the map it relates to 10 miles in the real world.The scale is usually shown in the bottom right corner of the map.
