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!!
