Let's go through the questions based on the timetable provided.

(a) Journey from the railway station to the market:

• The bus leaves the Railway station at 05:30 and arrives at the Market at 06:10.
• So, the journey takes 40 minutes.

(b) Time for the complete bus route:

• The bus starts at the Bus station at 05:20 and returns at 08:10.
• The total time is from 05:20 to 08:10, which is 2 hours and 50 minutes.

(c) Waiting time at the hotel zone for the next bus to the airport:

• The passenger arrives at the Hotel zone at 10:52.
• The next bus to the Airport arrives at 13:05.
• The waiting time is from 10:52 to 13:05, which is 2 hours and 13 minutes.

(d) Total journey time for Leroy:

• Leroy arrives at the Airport at 13:40 and waits for the bus to the Town square.
• The next bus from the Airport leaves at 16:00 and arrives at the Town square at 16:30.
• So, Leroy waits 2 hours and 20 minutes at the airport, and the bus journey takes 30 minutes.
• The total time, including waiting, is 2 hours and 50 minutes.
