**bobpursley**, Tuesday, September 25, 2007 at 5:40pmThe rate for the first is one loop per 5min, the other one loop per four minutes. The combined rate is the sum of these:

1loop= (lloop/5min + 1loop/4min)*time

time= 1/(1/5 + 1/4) minutes

This is somewhat tricky to get combined, if you wish, you can make decimas..

time= 1/(.2+.25)= 1/.45 and you take it from there.
