Answer:
The answer is 70 minutes.
Explanation:
The math section of the PSAT has two parts: one part (the calculator portion) is 45 minutes and consists of 31 questions which calculators would be allowed to use for solving; the other part (the no calculator portion) is 25 minutes and consists of 17 questions which calculators would not be allowed to use for solving.
Therefore, the total minutes students are given to complete the math section of the PSAT = 45 + 25 = 70.
