Question

A river is 2 meter deep and 45 m wide flowing at the rate of 3km/hr .Find the amount of water in m³ that runs into sea per minute​

Answer 1

ANSWER:-

3000/60 = 300/6 = 50 m/min

3 km/hr = 3000m/hr = 3000/60 = 50 m/minute

Breadth = 45 m

Length = 50m

Height = 2m

Amount Of Water = Volume

Volume = Length*Breadth*Height

= 45*50*2

= 90*50

= 4500 m³

Answer 2

A river is 2 meter deep and 45 m wide flowing at the rate of 3km/hr .Find the amount of water in m³ that runs into sea per minute

${\huge{\underline{Answer:-}}}$

${\sf{\color{green}{\underline{\underline{Given:-}}}}}$

Rate of water flow in a sea = 3 km / hour

$\leadsto$3000/ 60 m / min

$\leadsto$50 m / min

$\leadsto$Depth (h) of river = $2 m$

$\leadsto$Width (b) of river = $45 m$

Volume of water flow that runs into the sea in 1 min = $\sf\bold\color{red}{50 x 45 x 2 = 4500 m3}$

.°. in 1 minute, 4500 m3 water will fall in the sea.
