Answer: 17.04 km/L
Explanation:
Given: An automobile can travel 40.0 miles on one gallon of gasoline
That is 40 miles/ gallon
Now using the conversion factor :
1 mile = 1.61 km
Thus 40 miles =[tex]\frac{1.61}{1}\times 40=64.4km[/tex]
Alsousing the conversion factor
1 gallon = 3.78 L
Thus [tex]40miles/gallon[/tex] will be [tex]\frac{64.4km}{3.78L}=17.04km/L[/tex]
Thus the answer is 17.04 km/L.
