text: read this please and give me the answer you think is correct.? homer can type twice as fast as marge. together, they can type 100 pages in 3 h. how long does it take each person, working alone, to type 100 pages? this is simple algebra.  the rate thing 100 pgs / hr is a number as much as any number.  if we say x is the rate marge types then homer types at 2 * x and your equation is  100 pgs/ 3 hrs = (2 * x) + x = 3 * x  solving for x we get marge typing at 11.11 pgs/hr and homer typing at 22.22 pgs/hr - so marge will take 9 hours to do 100 pages on her own and homer 3 hours.
