Answer:

Area of river = depth × width

=3×40

$= 120 {m}^(2)$

amount of water that falls into the sea ⇒

Area of river × flow rate

$120 {m}^(2) * 2 \: (km)/(hr)$

$120 * \frac{2 * 1000 {m}^(2) }{(60)min}$

$4000 \: \frac{ {m}^(3) }{min}$

:.
${4000m}^(3)$ of water falls into the sea per min.

So,
${4000m}^(3)$

= 4000 × 1000 litres

= 4000000 litres

So, in 1 minute, water will fall into the sea is 4000000 litres.
