A river 3.5 m deep and 28 m wide is flowing at the rate of 2.4km per hour. How many liters of water will flow into the sea in 10 minutes

10 min = 600 sec

volume of water flow into the sea = 3.5 × 28 × 0.666667 ×600 = 39200 m³ or 39200×10³ lit

width = 28m

we have need to find out its area..because we directly can't findout its volume.

so area=depth*width

= 3.5 * 28 = 98 sq. m

flow of water in 10 minutes = area * velocity in minutes * time

98 * 2.4 * 1000(to convert it into metre) / 60 (to convert it into minutes) *10 = 39200 cubic mtr
