Reading a timetable

  • Timetable columns are journeys and rows are stopping points, so a single service is read down one column
  • Times are given in 24-hour form, and a blank entry means that service does not call there
  • A journey time is the difference between the departure and arrival entries in the same column
A bus timetable with four stops down the left and three columns of 24-hour departure times, so one column is one bus running through every stop and reading down a column follows a single journey

Local time and time differences

  • Places in different time zones record different local times for the same instant
  • A place ahead of another has its local time later by the difference, and a place behind has it earlier
  • Add the difference when travelling to a place that is ahead, and subtract when it is behind
  • Where a question gives a flight duration, apply the duration first and the time difference second, keeping the two steps separate
