First we calculate the efficiency in liters over kilometers so:

$(100)/(15)\frac{\operatorname{km}}{lt}=6.66\frac{\operatorname{km}}{lt}$

Now we can convert the units like

$6.66\frac{\operatorname{km}}{lt}\cdot(3.7854)/(1)\frac{lt}{\text{gal}}\cdot(1)/(1.6)\frac{\text{miles}}{\operatorname{km}}=15.75\frac{\text{miles}}{\text{gal}}\approx15.8(miles)/(gal)$
