Question 2

When Jessica takes the direct route to work, she gets there in 25 minutes if no train is at the railroad crossing. When a train is using the crossing, her travel time is 10 minutes longer. Her alternative is a route that takes 32 minutes to travel, but has no traffic signals or other delays. Assuming that shorter transit times are more desirable, which route will Jessica select if she uses the maximin criterion? Explain.

Answer to Question 1

C

Answer to Question 2

Alternative route; Assuming that shorter transit times are more desirable, Jessica's reason using the maximin criterion will follow these steps: If she takes the direct route, the greatest time it might take her to get to work is 35 minutes. If she takes the longer route, the greatest possible time is 32 minutes. Therefore, using the maximin criterion, Jessica will choose the longer route because it has the better of the worst possible travel times.
