Answer: 2:30 pm
Explanation:
Going backward, since he spent 1/2 hour - 30minutes from the cinema to home.
5:45 - 30 = 5:15pm.
5:15pm was when the movie finished.
The movie lasted for 2 1/4 hours = 2 hours, 1/4 hours -15 minutes
So the movie lasted for 2 hours, 15 minutes.
5: 15 - 2: 15 = 3:00pm
And it took him another 1/2 hours to cinema from his house
3:00pm - 30minutes = 2:30pm
