Waves on a string: speed

A $5\mathrm{.}0$ mm wire with a mass of $0\mathrm{.}084$ kgkg $$is attached to the mast of a sailboat. If the wire is given a "thunk" at one end, it takes $0\mathrm{.}095$ ss for the resulting wave to reach the other end.

Note:$$ in$$ the speed formula v $=$ F$/$$$F$/$$,$ the is calcalted as: total mass of$$ the string in kg $/$ total length$$ of the string in meters What is the speed of the wave in the wire? $$
