9-39 Baseball umpiring crews are currently in four cities where three-games series are beginning. When these are finished, the crews are needed to work games in four different cities. The distance (miles) from each of the cities where the crews are currently working to the cities where the new games will begin are shown in the following table

to

from Kansas Chicago Detroit Toronto

Seattle 1,500, 1,730, 1,940, 2,070

Arlinton 460, 810, 1,020, 1,270

Oakland 1,500, 1,850, 2,080, X

Baltimore 960, 610, 400 330

The X indicates that the crew cannot be sent to Toronto. Determine which crew should be sent to each city to minimize the total distance traveled. How many miles will be traveled if these assignments take place?
