QUESTION:-☃️

A river 3m deep and 40m wide is flowing at the rate of 2km/h. How much water will fall into the sea in a minute?

SOLUTION :-☃️

$\huge\boxed{\mathfrak{\blue{\fcolorbox{yellow}{pink}{Answer}}}}$

Here, Area of river = depth × width=3×40=120m²

amount of water that falls into the sea ⇒ area of river × flow rate

⇒120m² ×2km/hr

⇒120× (60)min2×1000m³

⇒4000 min m³

∴4000m³ of water falls into the sea per minute.
