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 $= \sqrt{3^{2} + 4^{2}} = 5 m$ $=sqrt{3^2 + 4^2} = 5m$ .
The distance travelled is just the sum of the three individual distances travelled $= 3 + 4 + 6 = 13 m$ $= 3 + 4 + 6 = 13m$ .
