Answer:
A=42.25
Step-by-step explanation:
6.5^2
For every liter she used, she drove 8 kilometers. In this problem you are finding the unit rate. In order to do this you divide 48 (kilometers) by 6 (liters of gasoline).
48 Divided by 6 equals to 6 Kilometers
—- —-
6 Divided by 6 equals to 1 Liter
For the second question you divide the liter by 6. Amelia used 0.1666 liters of gasoline per kilometer. 0.1666 is equivalent to 1/6.
Time taken
= 6000/1
= 6000s
= 100 min
= 1 hour 40 minutes
