Last Sunday, teams of runners took part in a charity event. The time taken, in seconds, to run 
was recorded, correct to 1 decimal place, for each runner. The times recorded for 11 runners from each of
the Gulls and the Herons are shown in the table.
Draw a back-to-back stem-and-leaf diagram to represent this information, with Gulls on the left-hand side.
