An automobile achieves a gas mileage of 30.5 mi/gal. how many kilometers can it travel on 1.5 l of gasoline?

Gas mileage = 30.5 mi/gal

Volume of gas = 1.5 l

Note that 1 liter = 0.264172 gallons

Therefore

1.5 l = (1.5 l) * (0.264172 gal/l) = 0.3963 gal

Distance traveled is (Gas mileage, mi/gal) * (Gal of gas)

= (30.5) (0.3963) = 12.087 mi

Answer: 12 mi (nearest integer)
