marcus aaron and jason went to a double feature movie. the show began at 1.45 pm and lasted for 4hrs and 27mins. at what time did the show end? would it be 6.14pm

Close, just add again.

6.27pm

Nope :)
After 4 hours it is 5:45. 15 minutes later it is 6:00. You have 12 minutes left, so 6:12. Do you get it or should I explain more?

I got 6:12pm but my teacher said it was wrong. She said since it was a double-feature you have to add the 4hours and 27min twice. That doesn't make any sense.

To find the end time of the movie, you need to add the duration of the movie to the start time.

The movie started at 1:45 pm and lasted for 4 hours and 27 minutes.

To calculate the end time, you can start by adding the 4 hours to the start time:
1:45 pm + 4 hours = 5:45 pm

Then, add the additional 27 minutes to the result:
5:45 pm + 27 minutes = 6:12 pm

So, the movie ended at 6:12 pm, not 6:14 pm.
