Maps can also be used to find out distances inside a locality.
Here is a map showing the houses of four children and position of 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

600 m
200 m
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 ice cream parlour?

Rohan's house is 2 km 800 m from Riya's house via ice cream parlour.

(b) Maya bought the ice cream and walked to give it to Gyan. How much distance did
she cover in total?

Maya covers 2.5 km in total.

(c) Who covered the longest distance to reach the ice cream parlour?

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: Map scale shows the relationship between 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 4 cm distance between two places on the map, it means the actual distance
between that places on the ground is 40 km.

This scale on the map is written as: Scale: 1 cm = 10 km.
