The map of India looks like a Rombus, doesn’t it?
Known:
The area of Rombus = (Product of Diagonals)/2
Distance = Speed x Time
For the diagonals, we need to calculate the distance between (North-South) & (East-West)
Assumption:
The area of the islands is considered to be insignificant, hence excluded.
The average speed of Trains in India ~ 50km/hr
Time taken to travel from North to South by Trains,
= Jammu to Delhi + Delhi to Kanyakumari
= 10hrs + 50hrs
= 60 hrs
Distance = 50 x 60 = 3000 KM
Time taken to travel from East to West by Trains,
= Ahmedabad to Delhi + Delhi to Itanagar
= 10 hrs + 40 hrs
= 50hrs
Distance = 50 x 50 = 2500 KM
Area of India,
= (Product of Diagonals)/2
= (3000 x 2500) / 2
= 7500000 / 2
= 3.75 million km sq
Actual Area of India = 3.28 million km sq.
