(Street plan): A city has two main roads which cross each other at the center 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
$1$
cm
$=200$
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
$2_{nd}$
street running in the North-South direction and
$5_{th}$
in the East-West direction meet at some crossing, then we will call this cross-street
$(2,5)$
. Using this conversion, find:
$(i)$
How many cross-streets can be referred to as
$(4,3)$
$(ii)$
How many cross-streets can be referred to as
$(3,4)$
.
