Maps can also be used to find distances inside a locality.
Here is a map showing the houses of four children and the position of an ice cream parlour.
Look it carefully.
3 km 1 km
Riya's Rohan's
300 m House 2 km 800 m 1 km House
Ice Cream Swati’s House 4 km
1 km Parlour 2 km
500 m 1.5 km

Gyan House
Maya's House
From the map, we can answer the following questions:
( a) How far is Rohan’s house from Riya’s house via the ice cream parlour?
Rohan’s house is 2 km 800 m from Riya’s house via the ice cream parlour.
( b) Maya bought an ice cream and walked to
give it to Gyan at his house. How much Knowledge Desk
distance did she cover in total? Cartography: The art and science of
Maya covered 2.5 km in total. drawing maps is called cartography.
A person who makes maps is a
( c) Who covered the longest distance to reach cartographer. It's a job that combines
the ice cream parlour from their house? geography, art, and mathematics.
Riya covered the longest distance to reach the ice cream parlour.
Components of a Map
A title, a key, direction and scale are components of a map.
Title: It gives the subject of a map, that is, what information the map contains.
Scale: The map scale shows the relationship between the distance on a map and the
corresponding actual distance. Places on a map are shown by shrinking the actual distance.
So, using the scale we can find the actual distance on the ground by measuring the distance
on a map.
For example, suppose 1 cm on the map equals 10 km on the ground.
If we measure a 4 cm distance between two places on the map, it means the actual
distance between those two places on the ground is 40 km.
This scale on the map is written as: Scale: 1 cm = 10 km.
