question: Movie A was one-fourth the length of Movie B. Movie B was 5 minutes longer than Movie C. Movie C was 1.25 hours. How many minutes long was Movie A?
answer: Movie C = 1.25 hours = 75 minutes
  Movie B = 75 + 5 = <<75+5=80>>80 minutes
  Movie A = (1/4) * 80 = <<(1/4)*80=20>>20 minutes
  Movie A was <<20=20>>20 minutes long.
