Let’s solve this step by step.
We need to find the
elapsed time between each “Start Time” and “End Time”. Elapsed time means how much time passed from start to end.
We’ll go row by row.
---
Row 1 (already done):
Start: 8:00 A.M. → End: 10:30 A.M.
From 8:00 to 10:00 is 2 hours. Then add 30 minutes →
2 hours 30 minutes ✔
---
Row 2:
Start: 10:00 P.M. → End: 11:30 P.M.
From 10:00 to 11:00 = 1 hour
Then 11:00 to 11:30 = 30 minutes
Total =
1 hour 30 minutes
---
Row 3:
Start: 2:00 P.M. → End: 5:00 P.M.
From 2:00 to 5:00 = 3 hours
No extra minutes →
3 hours
---
Row 4:
Start: 12:30 P.M. → End: 7:00 P.M.
From 12:30 to 6:30 = 6 hours
Then 6:30 to 7:00 = 30 minutes
Total =
6 hours 30 minutes
*(Alternative way: From 12:30 to 7:00 — count up: 12:30→1:30→2:30→3:30→4:30→5:30→6:30 = 6 hours, then +30 min to 7:00)*
---
Row 5:
Start: 4:00 A.M. → End: 11:00 A.M.
From 4:00 to 11:00 = 7 hours
→
7 hours
---
Row 6:
Start: 3:00 P.M. → End: 9:30 P.M.
From 3:00 to 9:00 = 6 hours
Then 9:00 to 9:30 = 30 minutes
Total =
6 hours 30 minutes
---
Row 7:
Start: 4:30 P.M. → End: 6:00 P.M.
From 4:30 to 5:30 = 1 hour
Then 5:30 to 6:00 = 30 minutes
Total =
1 hour 30 minutes
*(Or: 4:30 to 6:00 is 1.5 hours → same thing)*
---
Row 8:
Start: 12:00 A.M. → End: 12:00 P.M.
This is midnight to noon → exactly
12 hours
*(Note: 12:00 A.M. is midnight, 12:00 P.M. is noon — so half a day passes)*
---
Row 9:
Start: 1:00 P.M. → End: 1:30 P.M.
Only 30 minutes pass →
30 minutes
---
Now let’s write all answers in order:
Final Answer:
1 hour 30 minutes
3 hours
6 hours 30 minutes
7 hours
6 hours 30 minutes
1 hour 30 minutes
12 hours
30 minutes
