Martiza is studying for the citizenship test. There are 60 questions on the test. 30 are multiple-choice and 30 are fill-in-the-blank. It takes her 15 minutes to learn each multiple-choice question and 25 minutes each to learn the fill-in-the-blank questions. How many hours will she need to study before she is ready for the test?
Thoughts? Step-by-step reasoning:
The multiple - choice questions will take her a total of 30 * 15 = 450 minutes. The fill - in - the - blank questions will take her a total of 25 * 30 = 750 minutes. The test will take her a total of 450 + 750 = 1200 minutes to study for. Therefore, Martiza will need to study a total of 1200 / 60 minutes = 20 hours.
Thus, the answer is 20.
