5m. 13m.

Explanation:

Use Pythagoras to work out the resultant magnitude of displacement from the vectors. 6m South cancels out with 3m North to give overall 3m South.
Now you have a right angled triangle with side lengths of 3 & 4, and the hypotenuse is the resultant magnitude of displacement #=sqrt{3^2 + 4^2} = 5m#.
The distance travelled is just the sum of the three individual distances travelled #= 3 + 4 + 6 = 13m#.
