Worked Solution
Step 1: Add the hour part first.
10:30 a.m. + 1 hour = 11:30 a.m.
Step 2: Add the minutes.
11:30 + 45 minutes: 30 + 45 = 75 minutes
75 minutes = 1 hour 15 minutes
Step 3: Add the carried hour.
11:30 + 1 hour 15 minutes = 12:45? No — recheck:
11 hours + 1 hour (carry) = 12 hours; minutes = 15
End time = 12:15 p.m.
Answer: The programme ends at 12:15 p.m.
Correct answer: 12:15 p.m.
