Problem Solving (PS) | In the figure above, m is parallel to n, but n is not parallel to p.

If the traversals are also parallel, the distance between the parallel lines will also be 3.
For the lines to be parallel, the traversal has to be equal, else the lines can't be parellel.

Since z+w = 5, w = 5-3 = 2
Hence, z:w = 3:2
Hope that helps!
