  1. 2:3:4
  2. 4:3:6
  3. 3:4:6
  4. 6:4:3

Correct answer and explanation

Correct answer: 6:4:3

Explanation: āœ… Correct Answer: D. 6:4:3 šŸ“š Explanation: The time taken to travel a distance is inversely proportional to the speed. Therefore, the ratio of the time taken is (1 divided by 2) to (1 divided by 3) to (1 divided by 4). Multiplying by the LCM of the denominators (12), we get the simplified ratio 6:4:3. This means the car with the slowest speed takes the most time to travel the same distance.
