Man A and Man B have a business meeting at the airport. It is known that man A and man B live in different addresses. It is also known that both of them leave their home at the same time, and it is assumed that the running times of the busses they use, are independent. Man A has a travel time from his home to the airport, with an approximate normal distribution having the parameters: E(x) 35, and Var(x) 16, and for man B the corresponding parameters are 30 and 9
