Carla needs to compete her science homework. She has 20 pages to read and 14 questions to answer. If it takes Carla 10 minutes to read 4 pages, how many minutes will it take her to read the full assignment?
Carla has to read 20 pages and it takes her 10 minutes to read 4 pages so she needs to read 20/4 = <<20/4=5>>5 sets of 4 pages
It takes 10 minutes to read a 4 page set and she needs to read 5 sets of 4 pages so it will take her 10*5 = <<10*5=50>>50 minutes to read all the pages. Answer: \boxed{50}.
