Question

river to metre deep and 45m wide is follow at the rate of 3 km per hour find the amount of water that run into the river 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
