La obra de teatro cuya duración fue cerca de 1 hora y 55 min, terminó a las 9:55 pm .
For the conversion units of time, you need to know the relation between the units:
1 hour = 60 min = 3600 s
1 min=60 s
It's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.
The question gives:
The duration of the pay was 115 min.
The play started at 8 pm.
First, you should convert the duration of the play into hours and minutes.
1 h ----------- 60 min
x ------------- 115 min
60x=115
x=115/60
x=1.91 h
Then, you find 1.91h. In the other words, you have 1 hour and you should convert 0.91 h into min, as requested by the question.
1 h ----------- 60 min
0.91 ------- x min
x=0.91 * 60
x=54.6
x≅55
Therefore, the duration of the play was approximately 1 hour and 55 min.
Like the play started at 8 pm. You should sum the time of starting with the duration time. Then,
8:00 +1:55=9:55 pm
Thus, the play finished at 9:55 pm.
