For a fixed time limit for a quiz, the number of minutes m that a student should allow for each question on a quiz (assuming they are of equal difficulty) is inversely proportional to the number of questions n on the quiz. For a given time limit on a 16-question quiz, students have 2.5 min per question.
(a) Find an equation of variation. (b) How many questions would appear on a quiz in which students have the same time limit and have 8 min per question?
(a) An equation of variation is m=
