Correct answer and explanation

Correct answer: 15 : 10 : 6

Explanation: āœ… Correct Answer: A) 15 : 10 : 6 šŸ“š Explanation: Time taken is inversely proportional to speed. Therefore, the ratio of time is 1/2 : 1/3 : 1/5. Multiplying by the LCM of denominators (30), we get (30/2) : (30/3) : (30/5) = 15 : 10 : 6.
