The drama club is showing a video of their recent play. The first showing begins at 2:30 PM. The second showing is scheduled at 5:25 PM with a 1/2 break between the showings.
The video would be 2 hours and 25 minutes. First you would subtract 30 minutes from 5:25, 4:55. Then you figure out the difference in hours and minutes between 2:30 and 4:55.
