Answer:

[tex]42.34\ \text{miles per gallon}[/tex]

Explanation:

Given that,

A European automobile gas mileage is 18 km/L.

We know that,

1 km = 0.621 miles

and

1 L = 0.264 gallon

So,

[tex]18\ \dfrac{km}{L}=\dfrac{18\times 0.621\ miles }{0.264\ gallon}\\\\=42.34\ \text{miles per gallon}[/tex]

So, 18 km/L is equal to [tex]42.34\ \text{miles per gallon}[/tex].
