Question

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

Answer 1

The volume required is
`V  = 11.91 \ liters`

Step-by-step 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

`d = 142 * 0.6214 = 88.24 \ miles`

Generally the volume of gasoline needed is mathematically represented as

`V =  (d)/( v)`

=>
`V =  (88.24)/( 28.0 )`

=>
`V = 3.151 \ gal`

Converting to Liters

=>
`V = 3.151  *   3.78`

=>
`V  = 11.91 \ liters`
