Answer:
The play started at 5:10 PM.
Step-by-step explanation:
We are given the following in the question:
Length of first act = 45 minutes
Length of intermission = 55 minutes
Length of second act = 1 hour and 10 minutes
1 hour = 60 minutes
Thus, length of second act =
[tex]=60+10\\=70\text{ minutes}[/tex]
The second part ended at 8:00 PM. We have to find the starting time of play.
Starting time of play =
[tex]= 8-\dfrac{45+55+70}{60}\\=8 - 3\text{ hours} + 10\text{ minute}\\=5:10\text{ PM}[/tex]
Thus, the play started at 5:10 PM.
