there is an easy way of every thing
so let's see
divide 600 with 5
u will get 120
which means plane consume 120 litre petrol every minute
we have to find petrol consumed in 18 minutes so multiply 120 by 18
you get 2160 litres

Answer 2

$\underline{\underline{\red{\huge\mathfrak{ANSWER:}}}}$


$\underline{\underline{\red{\huge\mathfrak{2160}}}}$


$\textbf{EXPLAINATION}$


=> CONSIDER the quantity of fuel used in 18 minutes as ❓

=> So, the PROPORTION:

=> 600 : 5 : ❓ : 18

=> Mean × Mean terms= Extreme × Extreme terms

=> 5×❓ = 600 × 18

=> 5❓= 10800

=> ❓ = 10800 ÷ 5

=> ❓ = 2160 liters

therefore 2160 litres is needed to cover 18 minutes distance.
