Answer: it will cost £78.0672 to travel the 192 miles to Brighton.

Step-by-step explanation:

The minibus runs at 16 miles to a gallon of diesel. If there are 4.55 litres to a gallon and diesel costs £1.43 per litre, it means that the cost of a gallon of diesel would be

Therefore, the amount that it will cost to travel the 192 miles to Brighton would be

(192 * 6.5056) / 16 = £78.0672
