Complete question :
The expression 12g gives the number of kilometers a car can travel using g liters of gasoline.How far can this car travel on 6 1/2 liters of gasoline
Answer:
78 km
Explanation:
12g = Number of kilometers traveled using g litres of gasoline. - - - (1)
The expression shows that:
Kilometers per gallon = 12
Number of gallons used = miles per gallon * distance
Distance that can be traveled on a 6 1/2 lites of gas :
Here, g = 6 1/2
Substituting the value of g into the expression Given :
Distance = 12g
g = 6 1/2
Distance = 12(6 1/2)
Distance = 12(13/2) = 12(6.5)
Distance = 78 km
