Step-by-step explanation:
Given that: Rate of water flow = 3km/h= (3000/60) m/min =50 m/min
Depth (h) of river = 2 m
Width (b) of river = 45 m
Volume of water flowed in 1 min = Rate of water flow ×depth of river ×width of river = 50×2×45 = 4500 m3
Hence, in 1 minute, 4500 m3 water will fall in the sea.

[tex]Area \: of \: cross \: sector \: of \: river \\ \\ = 2×45 \\ \\ =90 {m}^{2} [/tex]
[tex]So, \: water \: flowing \: into \: \\ the \: sea \\ \\ = \frac{area \: of \: cross \: section}{times \: rate \: of \: flowing \: water} [/tex]
[tex] = 90 \times 3,000 \\ \\ = 27,000 \: {m}^{3} [/tex]
[tex]water \: flowing \: per \: minute \\ \\ = \frac{27,000}{60} \\ \\ = 45,000 \: {m}^{3} [/tex]
