During a school anniversary celebration, pupils were required to line along one side of the corridor to welcome the Guest-Of-Honor from the Foyer to the Hall. They would stand at an equal distance apart. A pupil would stand at the beginning of the corridor and another pupil would stand at the end. The corridor was 61 m long. During the rehearsal, 12 pupils were asked to line one side of corridor, from the beginning to the end. On the actual day, 7 pupils were absent and 3 pupils were asked to serve drinks In the parade square instead. Those pupils who remained would have to spread themselves out to line the entire corridor, from the beginning to the end. Find the new distance between every 2 pupils.
