Central tendancy measure for broadband internet speeds

#1
I have collected over 120 observations of broadband internet speeds achieved through my service provider. The values range from, 5 kilobits per sec. to 256 kbps.

I need to determine the average speed achieved.

I am wondering whether 'arithmetic mean' or 'harmonic mean' is the appropriate measure for this purpose, and why?
