question: In the first week, Judy read for 15 minutes each night before going to sleep. In the second week, she read a total of 100 pages. If she can read 2 pages per 1.5 minutes, how many pages did she read in two weeks?
answer: Every night, Judy reads 15 minutes/1.5 minutes = <<15/1.5=10>>10 sets of 2 pages.
  So, she read 10 x 2 = <<10*2=20>>20 pages every night in the first week.
  In the first week, she reads a total of 20 x 7 = <<20*7=140>>140 pages.
  Therefore, she read a total of 140 + 100 = <<140+100=240>>240 pages in two weeks.
