Suppose there are six people - J, M, R, S, T and W - who pass rumours among themselves. Each day J talks with M and W; M talks with J, R and S; R talks with M, S and T; S talks with M, R, T and W; T talks with R, S and W; W talks with J, S and T. Whatever people hear one day they pass on to others the next day.(a) Model this rumour passing situation with a graph.(b) How many days does it take to pass a rumour from J to S ? Who will tell it to S ?(c) Is there any way that if two people stopped talking to each other, then it must take three days to pass a rumour from one person to all the others ?
