Hey there again does anyone know this problem either??

You plan to go to portland to Tuscon. Let x be the distance in miles of any flight betwees Portland and Tuscon. What is a true statement about the mileage of any route from Portland to Tuscon? Assume that no route visits the same city more than once and that each route has no more than one layover.
*How many routes exist between Portland and Tuscon? What are they? Which route is the shortest?
*Can you write an inequality that represents the mileage of any route from Portland to Tuscon?
