Answer
$ 331. 6$ $km$
Work Step by Step
1. Convert miles/ gallon into km/liter by using the conversion factor $1 mile = 1.6093 km$ and $1 gallon = 3.7854 liters$.
$\frac{52 miles/ gallon \times 1.6093 km/mile}{3.7854 L/gallon}= 22.107 km/L$
2. Multiply obtained value by volume of the fuel to get the distance:
$ 22.107km/L \times 15 L = 331.6 km$
