Worked Solution
Step 1: We need to find the start time, so subtract the journey time from the arrival time.
Step 2: 10:35 pm − 45 minutes. Since 35 < 45, borrow 1 hour: rewrite as 9 h 95 min − 0 h 45 min (working with pm).
Step 3: 95 − 45 = 50 minutes; hours = 9 pm.
Answer: Start time = 9:50 pm.
Correct answer: 9:50 pm
