How Fast Does a Pulse Travel Along a Steel Wire?

[momogiri]

Problem
The figure shows two masses hanging from a steel wire. The mass of the wire is 60.0 g. A wave pulse travels along the wire from point 1 to point 2 in 24.0 ms.

Attempt
None yet, I don't really know how to tackle this :/

What does the speed of a wave traveling down a wire depend on? Look it up.

Ohh ok, so by using $$\sqrt{\frac{T_{N}}{\mu}}$$, I can find it :D
Thanks for your help
