Answer 1

Given:

3:15 pm - start of first showing.

30 minutes break;

20 minutes late - 2nd showing.

4:50 - start of second showing.

4:50 - 0:20 = 4:30 should be the start of the second showing.

4:00 - 4:30 = 1/2 hour break

3:15 - 4:00 = duration of the 1st showing. 45 minutes in all.

4:50 + 0:45 = 5:35 pm end of the 2nd showing.

Yes, the 2nd showing will be over by 6:30 pm.
