The amount of petrol required for the car to run 185km is 52.58
Given that for every 27 litres of petrol, the car can run for 95 km.
We are asked to find out how much petrol is required for the car to run 185 km.
95 km → 27 litres
185 km → ? litres
Let p denote the amount of petrol required by the car.
The number of kilometres car runs is increased from 95 km to 185 km.
The number of litres of petrol required will also increase when the number of kilometres run by the car increases.
The number of kilometres run by a car is directly proportional to the amount of petrol required.
Therefore, we have
95/185 = 27/p
⇒ p * 95 = 27 * 185
⇒ p = (27 * 185)/95
⇒ p = 4995/95
⇒ p = 52.58 (approximate to two places of the decimal point)
Therefore, 52.58 litres of petrol is enough for the car to run 185 km.
