Answer 2

Calculation of the End Time for the 3rd Movie Session

To calculate the end time for the 3rd movie session, we need to consider the duration of the movie and the break time between sessions.

Given: - Movie duration: 2 hours 5 minutes - Break time between sessions: 30 minutes

We can calculate the total time required for each movie session as follows:

Movie session time = Movie duration + Break time

Substituting the given values:

Movie session time = 2 hours 5 minutes + 30 minutes

To perform the calculation, we need to convert the movie duration and break time to a common unit, such as minutes:

Movie duration = 2 hours 5 minutes = 2 * 60 minutes + 5 minutes = 125 minutes Break time = 30 minutes

Now we can calculate the total time for each movie session:

Movie session time = 125 minutes + 30 minutes = 155 minutes

Since the first movie session started at 11:00, we can calculate the end time for the 3rd movie session by adding the total time for three movie sessions to the starting time:

End time for the 3rd movie session = Starting time + (Movie session time * (Number of sessions - 1))

Substituting the values:

End time for the 3rd movie session = 11:00 + (155 minutes * (3 - 1))

Calculating the result:

End time for the 3rd movie session = 11:00 + (155 minutes * 2) = 11:00 + 310 minutes

To convert the result back to hours and minutes, we divide the total minutes by 60 to get the hours and take the remainder as the minutes:

End time for the 3rd movie session = 11:00 + 5 hours 10 minutes = 16:10

Therefore, the 3rd movie session will end at 16:10.
