Part B: Fill in the Blank
Write the correct answer on each line.
1. If art class starts at 10:43 AM and lasts 40 minutes, it ends at 11:23 AM.
10:43 + 40 minutes = 11:23. Adding 17 minutes reaches 11:00, then 23 more minutes makes 11:23.
2. From 2:29 to 3:14, 45 minutes have passed.
2:29 to 3:14 = 45 minutes. From 2:29 to 3:29 is 60 minutes, minus 15 minutes = 45 minutes.
3. A game begins at 7:36 PM and ends at 8:11 PM. The game lasted 35 minutes.
7:36 to 8:11 = 35 minutes. From 7:36 to 8:36 is 60 minutes, minus 25 minutes = 35 minutes.
4. If it is 5:08 PM now and the show started 42 minutes ago, it started at 4:26 PM.
5:08 − 42 minutes = 4:26.
5. From 12:51 PM to 1:19 PM, 28 minutes have passed.
12:51 to 1:19 = 28 minutes. From 12:51 to 1:00 is 9 minutes, then 1:00 to 1:19 is 19 more minutes.
