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).

Answer :

The street plan is shown by the following figure.

(i) There is only one cross-street which could be referred to as (4, 3).

(ii) There is only one cross-street which could be referred to as (3, 4).
