Question
The fundamental resonance on a string is 60 cm length fixed at both ends is 440Hz. What is the speed of a wave traveling on this string?

Think about it. One wavelength is 60 cm.
It takes 1/440 sec to travel the length of the string.
speed = d/t = d*f = 60*440 = 2640 cm/s

Hmm. Forgot the fundamental wavelength is 120cm, not 60.
scale the velocity to account for that.
