Elapsed Time — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. From 10:05 to 10:40 is 35 minutes for Grade 3.
40 minus 5 equals 35 minutes elapsed.
2. 20 minutes after 12:25 is 12:45.
25 plus 20 equals 45 minutes past 12.
3. Lia walked from 3:40 to 4:10. She walked 30 minutes.
20 minutes reach 4:00, then 10 more makes 30.
4. From 2:00 to 2:55 is 55 minutes elapsed.
55 minus 0 equals 55 minutes elapsed.
5. 40 minutes after 5:30 is 6:10.
30 plus 40 is 70, so next hour plus 10.
6. Tom started at 7:15 and worked 25 minutes. He ended at 7:40.
15 plus 25 equals 40 minutes past 7.
7. From 11:20 to 11:50 is 30 minutes for Grade 3.
50 minus 20 equals 30 minutes elapsed.
8. 15 minutes after 4:50 is 5:05.
50 plus 15 is 65, next hour plus 5.
9. Emma read from 8:10 to 8:45. She read for 35 minutes.
45 minus 10 equals 35 minutes of reading.
