It is know as the map's scale. For example, a map with a 1:50,000 (one to fifty thousand) means that one centimetre measured on the map, represent 50,000 centimetres on the ground.
A bar scale is a fractional representation on the map showing the relationship between reality and the map, measured in given units, such as inches, feet or miles.
The SCALE of the map indicates the relationship between distances measured on a map and the actual distances.
Here is a little trick to know how to tell the difference between a large scale map, and a small scale map. A large scale map is a map where your house would look large on it. For example, a map of your neighborhood, or a map of you area. (You can see you house on this map) A small scale map is a map where your house would look small on it (or you can't see it at all), like a map of the world, or a map of Europe. So large scale = large house small scale = small house.
you use a map scale by measuring by inches
graphic scale, fractional scale, verbal scale

I don't know. Maybe you should study!
A bar scale is a fractional representation on the map showing the relationship between reality and the map, measured in given units, such as inches, feet or miles.
Graphic and fractional scales are two different things. A graphic scale on a map is a line marked with the lengths which represent real distances. It has a zero at one end. A fractional scale simply gives the ratio between map and real distances, e.g. 1: 10 000, so zero doesn't come into it.
(63360 x 5in) / 10in on map = 31,680 ==> the fraction scale is 1:31,680
1:100,000
Simple, you're dealing with two diferently scaled maps. Topographic maps are drawn to scale. This means that distances on a map are proportional to distances on the ground. For example, if two cities 20 miles apart are shown 4 inches apart on a map, then any other locations that are 4 inches apart on the map are also 20 miles apart. This proportion, the map scale, is constant for the map so it holds for any points on the map. In this example the proportion between equivalent distances on the map and on the ground is expressed as a scale of 1 inch = 5 miles, that is 1 inch on the map is equal to 5 miles on the ground. The simplest form of map scale is a VERBAL SCALE. A verbal scale just states what distance on a map is equal to what distance on the ground, i.e. 1 inch = 5 miles from the example above. Though verbal scales are easy to understand, you usually will not find them printed on topographic maps. Other types of scale used are the fractional scale and the bar scale. In the case of your question, 1in = 5miles equates roughly to a fractional scale of 1:312,500 and 1in = 2miles equates roughly to a fractional scale of 1:125,000
The three map scales are small scale, medium scale, and large scale. Small scale maps cover large areas with less detail, medium scale maps cover regions with more detail, and large scale maps cover smaller areas with the most detail.
It is 20 km * 6.5 = 130 km.
A fractional scale is a way that map makers tell you what distances on the map represent in real life. It does not use any units, so the scale might state 1:100000 [or 1/100000] which means that 1 unit on the map represents 100000 units in the real world. For example if you measure off 1 cm on the map, this represents 100000 cm (equivalent to 1000 m or 1 km) in the real world. See related link, below.
a verbal scale expresses distance as a statement, such as " one centimeter is equal to one kilometer" a graphic scale consist of the line that represents a certain distance, such as 5km or 5 miles. a fractional scale expresses ratios, such as 1:63 500. this means 1 unit on the map is 63 500 units on earths surface.
