Question

A river 2 m deep and 45 m wide is flowing at the rate of 3 km per hour,
Find the volume of water that runs into the sea per minute​

Answer 1

Answer:

Speed of river (l) =3km per hour (3 km convert into m is 3000m)

Breath (b)=45m

Height (h)=2m

volume of water runs into the sea in 1 hour : lbh =3000*45*2=270000m cube

So,

volume of water fall into the sea in 1 minute =270000/60=4500m cube
