Answer 2

Hey mate!

Here's your answer!!
-------------⤵️⤵️⤵️⤵️

Speed = 25km/h into m/min

$\frac{25 \times 1000}{60} = \frac{1250}{3} m \: per \: min$

In 40 minutes,

$\frac{40 \times 1250}{3} = \frac{50000}{3}$

Height = 10cm = 0.1m

Area it will irrigate,

$= \frac{5.4 \times 1.8 \times 5000}{3 \times 0.1} = 16200m {}^{2}$

Therefore, the area it can irrigate in 40 mins is 16200m².

Hope it helps you!
