Carla needs to complete her science homework. She has 20 pages to read and 14 questions to answer if it takes Carla 10 minutes to read four pages. How many minutes will it take her to read the full assignment would it be 85 minutes or 50 minutes or 35 minutes or nine minutes
If Carla takes 10 minutes to read four pages, it means she takes 10/4 = <<10/4=2.5>>2.5 minutes per page.
If she has 20 pages to read, it will take her 2.5 * 20 = <<2.5*20=50>>50 minutes to read the full assignment.
The correct answer is 50 minutes.
