Question

a river 3m deep and 40m wide is flowing at the rate of 2km per hour . how much water will fall into the sea in a minute?

Answer 1

HEY MATE HERE IS YOUR ANSWER

Depth of river = 3m

Width of river = 40m

So we have to make kilometres in metres see below and find water fall in a minute

So,

2km = 2000m
Now, 2000/60
We get, 100/3

So now apply the formula of volume

Which is, L ×B ×H

So now, find

=> 3 × 40 × 100/3

=> 4000m^3

Therefore water falls in a minute is 4000m^3

Answer 2

Breadth of river = 40m
Height / depth of river = 3m
Here the length of river is given in the form of rate of the river flow i.e. 2km/h
length = 2km = 2000m
Volume of river = 40×3×2000 =240000m^3
1 hour = 60 minutes
Water will fell in a min. = 240000/60
= 4000m^3
