here is the question:
Freida must take a 4-hour exam containing 200 questions, 50 of which are math. Twice as much time should be allowed for each math ques as for each other type of question. What is the total # of minutes she should allow for the math question?
1 hour and 35 minutes
2*M+ 150=4*60min
solve for m
1 hour and 35 minutes or 95 minutes
1 hour 35 minutes ðŸ¤
1 hour and 35 amigo
Hello
To find the total number of minutes Freida should allow for the math questions, we need to calculate the time for each math question and then multiply it by the number of math questions.
Let's start by finding the time allocated for each math question. Since twice as much time should be allowed for each math question compared to other types of questions, we'll divide the total exam time by the sum of the number of math questions and the remaining questions (200 - 50 = 150).
Exam time allocated for each question = Total exam time / Total number of questions
Since the exam time is given in hours and we need the time in minutes for each question, we'll convert the hours to minutes by multiplying by 60.
Exam time allocated for each question (in minutes) = (Total exam time in hours) * 60 / Total number of questions
Exam time allocated for each math question (in minutes) = (4 * 60) / 200
Now, we can find the total number of minutes Freida should allow for the math questions by multiplying the time allocated for each math question by the number of math questions.
Total time for math questions (in minutes) = Exam time allocated for each math question (in minutes) * Number of math questions
Total time for math questions = (4 * 60 / 200) * 50
Calculating the expression: (4 * 60 / 200) * 50 = 12 minutes
Therefore, Freida should allow 12 minutes for the math questions.
