Hi, thanks for the fast response. In fact, I’ve gone through that page, however, it’s still not clear for me why my answers can’t work :(

There was a PM too. So, I am addressing the question here itself. X has to be followed by Y. First monday is not followed by cleaning on first tuesday. Similarly, streets would be cleaned on 2nd and 3rd Monday but it will not be followed by Y. Only on fourth Monday and fourth tuesday, the cleaning of street will be done on consecutive days. Catch words are EVERY Monday and FOURTH Tuesday.

Hi Bunuel- I think answer should be C, but I am not sure.
Firstly, I assumed A=x and B=3x from Statement 1 but since I do not have actual speeds, Statement 1 wasn’t sufficient to determine the time in seconds.
Secondly, the average speed would not be of much help either from Statement 2. So, not sufficient
Lastly, putting the two statements together and applying avg speed formula- (2*S1*S2)/(S1+S2) to get the avg speed of each wheel.
Hence, concluded the both statements together are sufficient to answer the question.

Is my approach correct?

Also, if we solve further would the answer be 6 3/4 seconds using relative distance/relative speed concept?

Yes, the OA is C. Could you please post your reasoning in the thread itself? It's always better to post a solution in the topic rather than in the chat. Thank you.
