Correct question :
A river 3m deep and 40 m wide is flowing at the rate of 2 km per hour how much water will fall into the sea in a minutes.
1) 4000 m³
2) 2000 m³
3) 5000 m³
4) 20000 m³
Given :
To find :
Solution :
rate of flowing water = 2 km/hour
Length of water column in 1 hour = 2 km = 200 m
Given depth of river = 3 m
and width of the river = 40 m
Volume of water falling into the sea in 1 hour
=> I x b x h
=> 2000 x 40 x 3
=> 240000 m³
Volume of water falling into the sea in 1 minute
=> 240000/60
=> 4000 m³
∴ option 1 is correct option
