Math Problem Statement
In a certain exhibition, the time for the next visitor to come is exponentially distributed with a standard deviation of 1111 minutes. What will be the expected time (in minutes) for two visitors to arrive if one comes after the other? (Note that the arrival of a visitor is independent of the arrival of the previous visitor.)
