1its 1/2,
i know displacements can be superimposed but how can velocities be superimposed?
1.Two strings A and B ,of same material and Ra=2Rb,are stretched by the same tension.Transverse waves travel thru these strings,find the ratio of their velocities va/vb
2.HC Verma in his book mentions velocities of 2 interfering waves are superimposible too,how?

39well, regarding the second one, two waves can be superimposed even if they are interfering. the resultant position of a point would be sum of positions due to indivudual waves(of course with signs)
39v\alpha \sqrt{R} since materials are same and tension is same.
so \frac{v_{a}}{v_{b}}=\frac{1}{\sqrt{2}}
am i rite?
