The number of liters John will need to travel d kilometers = 15%2A%28d%2F100%29%29.    ANSWER


Or, which is the same,  


The number of liters John will need to travel d kilometers = %2815%2Ad%29%2F100.      ANSWER



          You may use ANY of the two answer forms - they are EQUIVALENT.


The question is answered,  and in this sense the problem is solved.


The other part of the condition,  related to price of the petrol,  is  IRRELEVANT  to the question

and is not used to get the answer.
