- A: 7 miles and 21 miles per gallon
- B: 57 miles and 19 miles per gallon
- C: 23 miles and 20 miles per gallon
- D: 32 miles and 35 miles per gallon
Correct Answer: B
Rationale: Use the formula g = d/f. For g = 3: Option B: 57/19 = 3. Check others: A: 7/21 = 1/3 ‰ 3; C: 23/20 ‰ 3; D: 32/35 ‰ 3. Thus, the correct answer is 57 miles and 19 miles per gallon.
