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].
