Area of cross section of river
= 2 x 45 = 90 m^2
So, water flowing into the sea= area of cross section x rate of flowing water
= 90 x 3000
= 270000 m^3
there water flowing per minute
= 270000 / 60 = 4500 m^3
= 2 x 45 = 90 m^2
So, water flowing into the sea= area of cross section x rate of flowing water
= 90 x 3000
= 270000 m^3
there water flowing per minute
= 270000 / 60 = 4500 m^3
