Let’s solve each row step by step. We’ll read the given time, add or subtract the elapsed hours, and write the new time.
---
Row 1:
End Time = 3:00 pm
Elapsed Time = -2 hours (so we go back 2 hours)
→ 3:00 pm minus 2 hours =
1:00 pm
Start Time =
1:00 pm
---
Row 2:
Start Time = 8:00 pm
Elapsed Time = +1 hour
→ 8:00 pm plus 1 hour =
9:00 pm
End Time =
9:00 pm
---
Row 3:
Start Time = 11:00 am
Elapsed Time = +3 hours
→ 11:00 am + 3 hours =
2:00 pm
(11 → 12 → 1 → 2)
End Time =
2:00 pm
---
Row 4:
End Time = 4:00 pm
Elapsed Time = -2 hours
→ 4:00 pm minus 2 hours =
2:00 pm
Start Time =
2:00 pm
---
Row 5:
End Time = 1:00 pm
Elapsed Time = -3 hours
→ 1:00 pm minus 3 hours:
1:00 pm → 12:00 pm → 11:00 am → 10:00 am
Start Time =
10:00 am
---
Row 6:
Start Time = 11:00 am
Elapsed Time = +2 hours
→ 11:00 am + 2 hours =
1:00 pm
End Time =
1:00 pm
---
Final Answer:
Row 1: Start Time = 1:00 pm
Row 2: End Time = 9:00 pm
Row 3: End Time = 2:00 pm
Row 4: Start Time = 2:00 pm
Row 5: Start Time = 10:00 am
Row 6: End Time = 1:00 pm
