Answer:
Petrol = 30 Litres ✬
✬ Distance = 225 km ✬
Step-by-step explanation:
Given:
A car consumes 10 litres of petrol to cover a distance of 150 km.
To Find:
How much petrol will it consume for covering distance of 450 ?
How much distance will it cover in 15 litres of petrol ?
Solution: Let's find out , how much petrol the car will consume for covering 1 km.
[ For this divide the distance, 150 km by 10 litres ]
➟ 150/10
➟ 15 km
So the car consumes 1 litre of petrol for covering distance of 15 km.
Now let , for covering a distance of 450 the car will consume x litres.
\implies{\rm }⟹ x = Distance/15
\implies{\rm }⟹ x = 450/15
\implies{\rm }⟹ x = 30 litres
Hence, the car will consume 30 litres of petrol for covering distance of 450 km.
________________________
Now , let car will cover a distance of x km in 15 litres of petrol.
x = 15 × distance covered in 1 litre
\implies{\rm }⟹ x = 15 × 15
\implies{\rm }⟹ x = 225 km
Hence, the car will cover a distance of 225 km in 15 litres of petrol.
