Answer:

To calculate the cost of travelling 110 km with a car that consumes N litres per kilometre, when petrol costs 72 cents per litre, use the formula:

Cost = (N × 110) × 0.72

Where:

- N is the car's gas consumption in litres per kilometre

- 110 is the distance travelled in kilometres

- 0.72 is the cost of petrol in dollars per litre

For example, if the car consumes 0.05 litres per kilometre, the total cost would be:

Cost = (0.05 × 110) × 0.72 = 5.5 × 0.72 = $3.96
