Step-by-step explanation:

a). Train leaves Westchester at 6:30.

    From the arrival - departure table in column (2),

    Arrival time of the train at middlewich = 6:51

b). Kate has to reach Southam before 9:00 am

    Therefore, time of the latest train that she can catch to get to work on time is 6:30 am

     By this train she can reach at 07:19 at Southam.

c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00

                                                                                         = 00:34

                                                                                         ≈ 34 minutes
