Question

1. The distance between a city in India and a city in Russia is 32,800 km. An aeroplane travels at a
speed of 800 km/hr. If it burns 500 litres of fuel in one hour, how many litres of fuel will be used
for this journey?​

Answer 1

Step-by-step explanation:

Given

Distance = 32,800Km , Speed = 800Km ,

First we will find total time taken by aeroplane between a city of India and Russia:-

$\small\bf We \: know, \: \: \large\boxed{\sf{Speed\:=\:\frac{Distance}{Time}}} \\ \large\implies\sf800 = \frac{32800}{time} \\ \implies\large\sf time = \cancel \frac{32800}{800} \\ \huge\therefore Time \: taken = 41 hour$

Now,

$\large\bf In \: 1 \: hour \: it \: burns \: = 500 \: litre \: petrol \\ \small\bf\:\: In \: 41 \: hour \: it \: burns=41 \times 500 = 20500 \: litre \: petrol$

Hence, 20,500 litres of fuel will be used for this journey.
