Question

A river 2 m deep and 36 m wide is flowing 2.4 km per hour. Find the quantity of water that runs
into the sea per minute.
​

Answer 1

Answer:

Speed of water flowing= 3km/hr

Into the sea

Given,

Depth(height) =2m Width(breadth) =45m

So we have to find the length,

For that, we've to convert km into meter and hour into min...

L

we know that,1km=1000m

then,3km=3000m

and, 1 hr =60min

So, length=3000/60

= 50m/min

Therefore, volm of water= 50x45x2

that runs into the sea per min

=4500m^3
