Sally drove 560 miles in her car.
The car travelled 34.5 miles for each gallon of petrol used.
Petrol cost £1.08 per litre.
1 gallon = 4.55 litres.
Work out the cost of the petrol the car used in October.
But its october first..?
(lol)
Answer?!
To find the cost of the petrol used by Sally's car in October, we need to determine how many gallons of petrol were used and then multiply that by the cost per gallon.
First, let's calculate the number of gallons used:
Sally drove a total of 560 miles, and the car traveled 34.5 miles for each gallon of petrol used. We can divide the total distance by the distance per gallon to find the number of gallons used:
Number of gallons = Total distance / Distance per gallon
Number of gallons = 560 miles / 34.5 miles per gallon
To get the cost per gallon, we need to convert the cost per litre to cost per gallon:
Given that 1 gallon is equal to 4.55 litres, we can calculate the cost per gallon:
Cost per gallon = Cost per litre * Litres per gallon
Cost per gallon = £1.08 * 4.55 litres
Now, we can calculate the total cost of the petrol used in October:
Total cost = Number of gallons * Cost per gallon
We substitute the values into the equation to find the cost:
Number of gallons = 560 / 34.5
Number of gallons = 16.23 (rounded to two decimal places)
Cost per gallon = £1.08 * 4.55
Cost per gallon = £4.91 (rounded to two decimal places)
Total cost = 16.23 gallons * £4.91 per gallon
Total cost = £79.62 (rounded to two decimal places)
Therefore, the cost of the petrol the car used in October is £79.62.
