(Street Plan) A city has two main roads which cross each other at the centre of the city.
These two roads are along the North-South direction and East-West direction. All the other streets of the city run parallel to these roads and are 200 m apart.
There are 5 streets in each direction. Using 1cm = 200 m, draw a model of the city on your notebook.
Represent the roads/streets by single lines.There are many cross-streets in your model.
A particular cross-street is made by two streets, one running in the North-South direction and another in the East-West direction.
Each cross-street is referred to in the following manner: If the 2nd street running in the North-South direction and 5th in the East-west direction meet at some crossing, then we will call this cross-street (2 , 5).
Using this convention, find
(i) How many cross-streets can be referred to as (4, 3).
(ii) How many cross-streets can be referred to as (3, 4).
