Drew has to finish his homework. He has 20 pages to read and 14 questions to answer. It takes him 10 minutes to read 4 pages. How many minutes will it take for him to read the full assignment?

Answer 1

Drew has to read 20 pages / 4 pages per 10 minutes = <<20/4=5>>5 sets of 10 minutes.
It will take him 5 sets x 10 minutes per set = <<5*10=50>>50 minutes to read the full assignment. Answer: \boxed{50}.
