Ashley Miller has three major routes to commute to work: take RiverView Street the entire way, take several back streets, or use the expressway. The traffic patterns are pretty complex. Under good conditions, RiverView Street is the fastest route; however, when it is congested, one of the other routes is usually preferable. Over the past two months, Ashley has tried each route several times under different traffic conditions. Her travel time to work $($in minutes$)$ is summarized in the following table.
