Answer:
3 hours and 24 minutes
Explanation:
Each our is 60 minutes long, so we have to times 60 by x until we get to 204, or close to it.
The closest we can get to 204 is 180, which is 60 times 3, hence the 3 hours.
Now we have to do 204-180, which is 24.
So the movies is 3 hours and 24 minutes long.
