Step-by-step explanation:

Total petrol consumption of the journey=

Total distance travelled ÷ Average petrol consumption

$= 280 \div 35 \\ = 8 \: gallons$

Given 1 gallon = 4.5 litres,

$8 \: gallons \: = 8 \times 4.5 \\ = 36 \: litres$

Total cost of petrol for this particular journey = Petrol consumed x cost of 1 litre of petrol

$= 4.5 \times 49 \\ = 220.50 \: dollars$
