Problem 1
Problem 1 A train journey to London.
GNER have decided to run a better, more regular, train service between
Aberdeen and London. Not before time I hear some readers say. Trains
leave Aberdeen for London on the hour, every hour, day and night and
similarly trains leave London for Aberdeen on the hour, every hour.
Every train takes seven and three quarter hours for the journey. They
all stop at Leuchars (great!) which is two hours journey time from
Aberdeen. Jonathan boards a train at Leuchars for London. How many
London to Aberdeen trains will Jonathan pass on his journey south.
