Answer :


To find out how long the movie was just

movie started at 11:30am

12:30pm would be 1 hour

1:30 pm would be 2 hours

2:00 pm would be 2 1/2 hours or 2 hours and 30 minutes

2:12 pm just add 12 minutes to 30 minutes, 12 + 30 = 42 minutes

So the movie lasted 2 hours and 42 minutes.

Hope this helps. :)
