To find when both buses will next arrive at the same time, we need to find the least common multiple (LCM) of their arrival intervals, which are 21 minutes for the Wilkenson bus and 15 minutes for the Harris Road bus. The LCM of 21 and 15 is 105 minutes. Since both buses arrive together at 5:07 AM, adding 105 minutes to this time gives us the next simultaneous arrival time. 5:07 AM + 105 minutes = 6:52 AM.
