Question

15. (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).​

Answer 1

Step-by-step explanation:

Both the cross-streets are marked in the above figure. They are uniquely found because of the two reference lines we have used for locating them.
