Question

water in a river to metre deep 45m wide is flowing at the rate of 3 km per hour find the amount of water in cubic metre that Run into the sea per minute

Answer 1

Answer:

Step-by-step 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
