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 reach 4 pages how many minutes will it take her to read the full assessment?
85 minutes
50 minutes
9 minutes
35 minutes
If Carla can read 4 pages in 10 minutes, then she can read 1 page in 10/4 = 2.5 minutes.
