Your travel times are given in UTC, so, your answer is 07:27:38 UTC  (I 
think you tried to add the arrival time to the start time??)    it took 
about 891.60 seconds for the P wave to arrive at your location!!  
07:12:47 UTC plus 891.60s = approx. 07:27:38 UTC ,,,,   891.6/60 = 14.86 
minutes,,,  for rough distance, 69*125.1 = approx. 8632 miles,,  or 
111.12 * 125.1 = approx. 13901.112 km!!
