Since there is a short difference between the starting and ending times, we calculate the schedule of each commercial and then compare the broadcasting times.
Commercials of the broadcast Ramon is watching air at:
7.17, 7.34, 7. 51, 8.08, 8.25, 8. 42 8.59 a.m.
Commercials of the broadcast Justice is watching air at:
7.14 7.28 7.42 7. 56 8.10 8.24 8.38 8.52 a.m.
