From the time schedule in the table
a)The first train arrives in London at 0848
b) The time it takes 0710 train from Norwich to arrive at Colchester is
Time lapse between 0710 and 0812
= 62 minutes or 1h 2mins
c) Cary gets to Norwich Station at 0750
At this time, the next available train at 0755 has no terminal in Colchester. Therefore, he has to wait for the next available train at 0805.
