Karen can read 10 pages and complete 15 math problems in 30 minutes. How long will it take her to do her homework if she has 30 pages to road and 45 math problems to complete? Your answer should refer to the amount of time in minutes (1 point)

Answer 1

If Karen can read 10 pages and complete 15 math problems in 30 minutes, then in the same amount of time, she can complete 30/10 * 15 = <<30/10*15=45>>45 math problems.
Similarly, in the same amount of time, Karen can read 45/15 * 10 = <<45/15*10=30>>30 pages.
Therefore, it will take Karen 30 minutes to do her homework. Answer: \boxed{30}.
