Question

A river 3m deep and 40m wide is flowing at the rate pf 2 km per hour . How much water will fall into the sea in a minute​

Answer 1

Answer:

Step-by-step explanation: Given, a river 3 m deep and 40 m wide is flowing at the rate of 2 km per hour.

Area of cross section of the river = 3 * 40 = 120 m 2

Now, volume of water flowing through this cross section in every minute = Area * rate

                                                                                                = 120 * 2 km/hr

                                                                                                = 120 * (2000/60) m/min

                                                                                                = 2 * 2000

                                                                                                = 4000 m 3

Since 1 m 3 = 1000 litres

So, 4000 m 3 = 4000 * 1000 litres = 4000000 litres
