In Europe, gasoline efficiency is measured in km/L. If your car's gas mileage is 28.0 mi/gal , how many liters of gasoline would you need to buy to complete a 142-km trip in Europe

The volume required is  

Explanation:

From the question we are told that

  The cars mileage is  v =  28.0 mi/gal

   The  distance is  d  =  142 km

Converting the distance from km to  miles

Generally the volume of gasoline needed is mathematically represented as  

=>    

=>    

Converting to  Liters

    =>  

     =>  

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
