Worked Solution
Step 1: Start time is 3:45 p.m. Duration is 45 minutes.
Step 2: Count to the next hour first.
3:45 p.m. + 15 min = 4:00 p.m. (used 15 of the 45 minutes)
Step 3: Add the remaining duration.
45 − 15 = 30 minutes remaining.
4:00 p.m. + 30 min = 4:30 p.m.
Answer: Siti finishes at 4:30 p.m.
Correct answer: 4:30 p.m.
