Question

Mr. Cho reached his office at 9:10 am. He took 37 minutes to check his emails and 1 hour and 38 minutes to write a report. Then he attended a meeting until he left for lunch at 12:30pm. How long did the meeting last?

Answer 1

Answer: the meeting lasted for an hour and 5 min.

Explanation:

1. 9:10am + 37min = 9:47am
2. 9:47am + 1hour = 10:47am
3. 10:47am + 38min = 11:25am
4. 12:30pm - 11:25am = 1hour, 5min

Therefore, the meeting lasted for an hour and five minutes.
