Hi, Let's say I have cars passing a point as a Poisson process with having stationary flow of 100 cars/hr. How would I go about finding the expected amount of time needed to observe one headway (time between cars) larger than three times the mean headway? Thanks!

I assume you know how to find the mean headway. What's the probability that no car passes in a period three times as long?
