I'm not sure about your speed  question, Harry, but here's a guess:  The 
technology for making the heads  improved so much by the time audio cassettes 
came along that you could get up to  20 kHz at 1-7/8 ips.  At the time 
reel-to-reel machines were in use, head  technology wouldn't have been as far 
    For a while, back in the 1960s, I  worked with 120 ips machines that 
pulled 2-inch tape, for high-resolution video  and multiplexed telemetry 
signals.  Amazing stuff.
    Wikipedia has a nice write-up on tape  recorders:

The one  thing that has never been explained to me though, is back in the
day's of  reel-to-reel tapes, we were told that for superior sound, one
should record  music at 7 1/2 ips rather than 3 3/4 ips and most machines 
both speeds  available.on them.

Yet, when audio cassettes came along, they were  recorded at 1 7/8 ips

Doesn't that kind of contradict the theory  applied to the reel-to-reels of
getting superior sound at the higher  speed?.

Someone once told me that professional studios even had the  capability of
recording reel-to-reels at 15 ips

I'm sure the answer  is quite simple and I will not be in the least bit
embarassed if it has to  be explained to me, otherwise I would not have even
brought up the  subject.in the first place
