Answer 1

$\sf{\huge{\underline{\red{Given :-}}}}$

• A car can cover 320 km on 12 litres of petrol .

$\sf{\huge{\underline{\orange {To\:Find :-}}}}$

• Distance is needed for the car to cover a distance of 480 km.

$\sf{\huge{\underline{\pink {Solution :-}}}}$

According to the question,

A car can cover 320 km on 12 litres of petrol .

1 km on = 12 / 320 litres of petrol .

For 480 km petrol required

➝$\dfrac{12}{320}$ × 480

➝ 12 × 1.5

➝ 18

For, travelling a distance of 480 km a car required 18 litres of petrol.

Answer:

${\Large\dag \large\underline\frak \red{Given}}$

• ↝ A car can cover 320 km in 12 litres of petrol

${\Large \dag \large \underline\frak \red{To \: Find }}$

• ↝ How much distance is needed for the car to cover a distance of 480 km..

${\Large\dag\large \underline \frak \red{Solution}}$

$\textsf{∵ 320 km covered in 12 litre petrol.}$

$\because \sf1 \: km = \dfrac{320}{12}$

$\sf{ \because 480 \: km = \dfrac{12 \times 480}{320} }$

$\sf \because 480 \: km = { \cancel \dfrac{5760}{320} }$

$\bf{ \therefore 480 \: km = 18 \: km}$

${\Large \dag\large \underline \frak \red{Therefore}}$

• ↝ 18 litre of Petrol is needed for the car to cover a distance of 480 km..
