A river 3 m 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 minute?
Rate of water flow = 2 km per hour
= (
) m/ min
= (
) m/ min
Depth (h) of river = 3 m
Width (b) of river = 40 m
Volume of water flowed in 1 min = (
* 40 * 3)
= 4000 m3
Therefore, in 1 minute, 4000 m3 water will fall in the sea
