An individual is planning to take an 600-mile trip between two large cities. Three possibilities exist: air, rail, or auto. The person is willing to pay $25 for every hour saved in making the trip. The trip by air costs $450 and travel time is 6 hrs, by rail the cost is $400 and travel time is 10 hrs, and by auto the cost is $250 and travel time is 15 hrs. (a) Which mode is the best choice? (b) What factors other than cost might influence the decision regarding which mode to use?
What will be an ideal response?
Determine the total cost (initial cost plus time cost) for each mode.
Total Cost(air) = 450 + (6 × 25)
Total Cost(air) = $600
Total Cost(rail) = 400 + (10 × 25)
Total Cost(rail) = $650
Total Cost(auto) = 250 + (15 × 25)
Total Cost(auto) = $625
From the above analysis, it appears that the best mode to choose to make this trip is air. Other factors to consider, other than costs, when selecting a mode to travel might include the following: personal comfort the modes have to offer, whether additional connections need to be made to reach the final destination, the level of stress that can be anticipated by traveling by that mode, or whether the reason for travel is for business or pleasure.
