Question

In November, Hilary drove 580 miles in her car. The car travelled 33.5 miles for each gallon of petrol used. Petrol cost £1.09 per litre. 1 gallon = 4.55 litres. Work out the cost of the petrol the car used in November.

Answer 1

The cost of petrol used in November is £86

Explanation:

Here, we are interested in calculating the cost of the petrol the car used in the month of November.

We proceed as follows;

Total miles driven = 580 miles

Now, on a gallon of petrol, the car will travel 33.5 miles

Thus, the amount of gallon of petrol

used for 580 miles will be 580/33.5

Let’s convert this to liters

Since 1 gallon is 4.55 liters, 580/33.5 gallons will be 580/33.5 * 4.55 = 78.78 liters

now the cost of 1 liter is 1.09, the cost of 78.78 will be 78.78 * 1.09 = 85.87

To the nearest pounds, we have the cost as £86
