Let us consider distance between Sacramento from Los Angeles be x.
Statement 1:
A car drove the distance on one tank at 28 miles per gallon, but we are not told the tank size.
So we cannot find the distance.
Not sufficient.
Statement 2:
A car averaged 50 mph and arrived in 8 hours → distance = 50 × 8 = 400 miles.
Sufficient.
Answer: Option B as statement 2 is sufficient.

Deconstructing the Question
We need to find the distance (\(D\)) between Sacramento and Los Angeles.
***
Analyze Statement (1)
"A car that obtains 28 miles per gallon drove the distance on exactly one tank of gasoline."
Formula: \(Distance = (Miles \ per \ Gallon) \times (Gallons \ in \ Tank)\)
\(D = 28 \times (\text{Tank Capacity})\)
We do not know the capacity of the tank (it could be 10 gallons, 15 gallons, etc.). Therefore, we cannot calculate the specific distance.
INSUFFICIENT
***
Analyze Statement (2)
"Another car averaged 50 miles per hour and arrived in 8 hours."
Formula: \(Distance = Speed \times Time\)
\(D = 50 \times 8 = 400 \text{ miles}\)
We have a unique value for the distance.
SUFFICIENT
***
Answer: B
