In November, Hillary drove 580 miles in her car. The car traveled 33.5 miles for each gallon of petrol used. Petrol costs £1.09 per litre.

1 gallon = 4.55 litres.

Work out the costs of the petrol the car used in November.

Step-by-step explanation:

First we divide the number of miles Hillary drove in November by the number of miles per gallon to figure out how many gallons of petrol she used.

580/33.5 = about 17.3 gallons of petrol

Next, we multiply the gallons of petrol by a liters to figure out how many liters she used.

17.3 x 4.55 = about 78.8 litres

Finally, we multply the number of litres Hillary used by the cost per litre

7/2

(decimal: 3.5)
