finding speed of transverse waves on a guitar string

The D note (at a frequency of 588 ) from a trumpet causes a guitar string to vibrate in its second overtone with large amplitude. The vibrating portion of the guitar string has a length of 64.0 . What is the speed of transverse waves on the guitar string? The way I've been trying to accomplish this problem is by saying tat ...continues
