Question

a river 3.5m deep and 25m wide is flowing at the rate of 2.4km per hour .how many litres of water will flow in the sea in 5min

Answer 1

distance = 2.4×1/12 = 0.2 km = 0.2×1000 = 200m
volume = lbh
3.5×25×200
35×25×20
17500 m^3
1m^3 = 1000 l
17500000l

Answer 2

Answer:

0.7 l

Step-by-step explanation:

WE CAN CONSIDER LENGTH AS 2.4m ie 2400m

then volume =lbh

                     = 3.5*25*2400

                    = 210000m^3

therefore in litres =210L

                          THEREORE WATER FLOWING 5 MINUTES

                              = 210/5*60

                      = 0.7 L
