Question
A mathematical examination started at 7:00 a.m. and lasted for 2 and a half hours. What time did it end?
Solution
The examination started at 7:00 a.m. and lasted for 2 and a half hours.
Step 1: Convert the duration of the examination into minutes. 2 hours is 120 minutes and half an hour is 30 minutes. So, 2 and a half hours is 150 minutes.
Step 2: Add the duration of the examination to the start time.
7:00 a.m. + 2 hours = 9:00 a.m. 9:00 a.m. + half an hour = 9:30 a.m.
So, the examination ended at 9:30 a.m.
