Question

Water in a canal, 5·4 m wide and 1·8 m deep, is flowing with a speed of 25 km/hour. How much area can it irrigate in 40 minutes, if 10 cm of standing water is required for irrigation ?

Answer 1

Answer:

Heyy

hope u got it

ANSWER IS 1620000 m

OR

1620 Km

Answer 2

We know that Distance=speed×time

height =S×t=25000×40/60=1000000/60=100000/6m

volume of water flowing out in 40 min = volume of field irrigated

l×b×h=area of irrigated field× height of standing water

5.4×1.8×100000/6=A×10/100

A=5.4×1.8×100×10000/6

A=0.9×1.8×1000000

A=16,20,000 square meters 162 hectares

Hope it helps you....
