A train leaves at 09:40 and the journey takes 2 hours 35 minutes. A passenger needs 20 minutes to travel from the station to a meeting that starts at 13:00. What is the latest train departure that would allow arrival by 13:00?
Answer and explanation
Correct answer: C. 10:05
- Step 1: Work backwards: arrive at station by 12:40. Step 2. 12:40 minus 2 h 35 min = 10:05. Answer: 10:05. Why not the others: 10:00 is too early to be latest but gives an earlier arrival; 10:25 arrives at 13:00 at the station and then 20 minutes late; 09:55 is not the latest.
