1.	The other two sides.38. Water in a canal 6 m wide and 1.5 deep, is flowing with a speed of 10 km/h. How much area will be irrigate in 30minutes, If 8 cm of standing water is needed ?
Answer» Answer: 562500 m² Step-by-step explanation: Surface area of the opening of the canal: Area = 6 m x 1.5 m = 9 m² Speed of the water that will FLOW out in 30 mins in metres: 1 HOUR = 10 km 30 mins = 10 ÷ 2 = 5 km = 5000 m Find the amount of water that are flowed out in 30 mins: Total water flowed = area x speed Total water flowed = 9 x 5000 = 45 000 m³ Find the area of the water after 30 mins: height = 8 cm = 0.08 m Area = 45 000 ÷ 0.08 = 562500 m²

Answer:

562500 m²

Step-by-step explanation:

Surface area of the opening of the canal:

Area = 6 m x 1.5 m = 9 m²

Speed of the water that will FLOW out in 30 mins in metres:

1 HOUR = 10 km

30 mins = 10 ÷ 2 = 5 km = 5000 m

Find the amount of water that are flowed out in 30 mins:

Total water flowed = area x speed

Total water flowed = 9 x 5000 = 45 000 m³

Find the area of the water after 30 mins:

height = 8 cm = 0.08 m

Area = 45 000 ÷ 0.08 = 562500 m²
