This should give you exactly 6 lpi @ 10pt

   \setupbodyfontenvironment[10pt][interlinespace=12bp]

The average character width in times roman is only a  little over 4pt
when loaded at 10pt, resulting in more than 18cpi, so you could try
to explain to them that the 10pt and 15cpm contradict eachother.

But I guess they do not really expect you to do anything with the cpi 
statement, unless you are using a typewriter.
