Question

A river 1.5 m deep and 36 m wide is flowing at the rate of 3.5 km per hour. The amount of water
that runs into the sea per minute (in cubic metres) is _______.

Answer 1

Answer:

Step-by-step explanation:

depth = 3.5m

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
