Answer
8.6 km
Work Step by Step
1. Convert miles/ gallon into km/liter by using the conversion factor $1 mile = 1.6093 km$ and $1 gallon = 3.7854 liters$.
$\frac{57 miles/ gallon \times 1.6093 km/mile}{3.7854 L/gallon}= 24.2326 km/L$
2. Multiply obtained value by volume of the fuel (355ml = 0.355L) to get the distance:
$ 24.2326 km/L \times 0.355 L = 8.6 km$
