<PRE><B>Question 1020775</B>
The middle most flag has 13 flags to the right and 13 flags to the left, then
:
the total distance she travels is 2 * ( 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26) = ?
:
the sum of the even integers is n(n+1), our n is 13, then
: 
total distance = 2 * (13(13+1)) = 364
:
