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 4 pages how, how many minutes will it take he rto read the full assignment.
First, we need to determine how many sets of 4 pages Carla will read to complete the 20-page assignment. This can be found by dividing the total number of pages Carla needs to read (20) by the number of pages Carla can read in 10 minutes (4): 20/4 = <<20/4=5>>5 sets of 4 pages.
Next, we need to determine how long it will take Carla to read each set of 4 pages: 10 minutes/set x 5 sets = <<10*5=50>>50 minutes.
Finally, we add up the time it takes Carla to read the sets of 4 pages to find the total time it takes Carla to read the full assignment: 50 minutes. Answer: \boxed{50}.
