    Explanation:

    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

    Hence, option 1 is the correct answer.
