Petrol cost £1.09 per litre

1 gallon= 4.55 litres

work out the cost of petrol used in the car in November

Answer 1

Answer:

85.85 pounds

Step-by-step explanation:

distance travelled : 580 miles

mileage : 33.5 / gallon

gallons used : distance travelled / mileage

= 580/33.5 = 17.31 gallons

1 gallon = 4.55 litres

17.31 gallons = 4.55 x 17.31 = 78.76 litres

cost of 1 litre of petrol : 1.09/litre

cost of 78.76 litres = 1.09 x 78.76 = 85.85 pounds

Answer 2

Answer:

price of 1 gal = price of one lite x number of liters in one gal.

so the price of 1 gallon = 4.55 x 1.09

=£ 4.95

now

33.5 miles in 1 gallon

1 mile in 1/33.5 gallon

580 miles in 1/33.5 x 580

= 17.31 gallons

hillary used 17.31 gal petrol in the month of November to drive 580 kms .

price of 1 gallon is £ 4.95

price of 17.31 gallons of petrol is 17.31 x 4.95 =. £ 85.70
