In a surgical department, there are 4 operating rooms: 1, 2, 3, and 4. In the morning, they were all empty. At some point, a surgery started in operating room 1, after some time in operating room 2, then some time later in room 3, and finally in room 4.

All four surgeries ended simultaneously, with a total duration of 2 hours and 7 minutes. 18 minutes before the completion of all surgeries, the total duration of the ongoing surgeries was 60 minutes; and 15 minutes before that, it was 25 minutes. Determine in which operating rooms the durations of the surgeries can be established based on this information, and in which ones it cannot.
