: (1) When n is an even number, p should be located anywhere between the first station and () station; When n is odd, p should be at the first stop; (2) According to the geometric meaning of absolute value, the minimum value of | x-1|+| x-2 |+| x-3 |+…+| x-6 17 | is the minimum sum of the distances between 617 points. According to the conclusion of the problem 1, when x = 309, the minimum value and minimum value of the original formula are | 309-1|+| 309-2 |+| 309-3 |+…+| 309-308 |+0 | 309-3/respectively. 08+307+306+…+ 1+ 1+2+…+308=308×309=95 172
