please give me right answer​

Answer 1

Answer:

d) 10000 ltr

Step-by-step explanation:

Area of cross section of river =3*40=120 sq m

Now the running rate =5m/h

so

volume covered by water=120*5=600 cubic metre

now amount of water drain into sea=600000 ltr/h

so amount of water per minute =600000/60=10000 Ltr
