Given:
A car can travel 3.5 km on 30 litres of petrol.
To find:
The distance a car can cover if it has 50 litres of petrol in its tank.
Solution:
We have,
On 30 litres, a car can travel = 3.5 km
On 1 litre, a car can travel = [tex]\dfrac{3.5}{30}[/tex] km
On 50 litres, a car can travel = [tex]\dfrac{3.5}{30}\times 50[/tex] km
= [tex]\dfrac{3.5}{3}\times 5[/tex] km
= [tex]\dfrac{17.5}{3}[/tex] km
[tex]\approx 5.83[/tex] km
Therefore, a car can travel 5.83 km on 50 litres.
