Question

The flow of water in a river is 3 km/h.If the river is 2 m deep and 45 m wide,then find the quantity of water that runs through a given point in the river per minute?

Answer 1

hlo mate ✌️

Area of cross section of river= 2 x 45 = 90 m²

so, water flowing into the sea= area of cross section x rate of flowing water

                                               = 90 x 3000

                                               = 270000 m³

there water flowing per minute= 270000 / 60 = 4500 m³

Hope it helps.
