Question

a river to metre Deep and 45m wide is flowing at the rate of 3 km per hour find the volume of water that runs into the sea per minute

Answer 1

Hello Mate!

Volume of water flowing = 2 m × 45 m × 3 km/hr

Volume of water flowing = 2 m × 45 m × 3000 m/hr

Volume of water flowing = 27000 m³/hr

Volume of water flowing in 1 hr = 27000 m³

So, in 60 mins water flow = 27000 m³

In 1 min the Volume of water flow will = 27000 m³ / 60

Volume of water flowing per minute = 4500 m³

Hence 4500 m³ water will flow per minute in river.

Have great future ahead!
