Uniform Distribution Problem on Efficiency
up vote

favorite
A bus travels between two cities $A$ and $B$ which are $100$ miles apart. If the bus has a breakdown, the distance from the breakdown to city A has a Uniform Distribution over $(0,100)$. There is a bus service station in city $A$, city $B$ and in the center of the route between $A$ and $B$. It is suggested that it would be more efficient to have the three stations at $25,50$ and $75$ miles, respectively, from $A$.
The question asks if the second arrangement is more efficient, I know how to calculate the probabilities, my intuition tells me that the second system is better, but can’t seem to come up with a way to conclusively state that either one will be better, can anyone help?

Perhaps you should try to calculate the expected value for the distance between the disabled bus and the nearest service station for the two cases.
