Answer 1

`42.34\ \text{miles per gallon}`

Step-by-step 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,

`18\ (km)/(L)=(18* 0.621\ miles )/(0.264\ gallon)\\\\=42.34\ \text{miles per gallon}`

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