To solve the inequality 6x - 2 ≥ 3x + 10, subtract 3x from both sides to get 3x - 2 ≥ 10. Then add 2 to both sides: 3x ≥ 12. Dividing both sides by 3 (a positive number) gives x ≥ 4. Therefore, the solution interval is [4, ∞), which corresponds to option C.

If Haroon uses 25% more petrol each day, the daily consumption increases by a factor of 1.25. The total petrol amount remains the same, so the new duration is 10 ÷ 1.25 = 8 days. However, this calculation is incorrect; let's re-examine: If the original daily usage is x, total petrol = 10x. New daily usage = 1.25x. Days = total petrol ÷ new daily usage = 10x ÷ 1.25x = 8 days. So the correct answer is 8 days, which corresponds to option C, not B. Correcting answer to C.
