Step-by-step explanation:
So the number of questions in an exam varies with the number of minutes to take the exam.

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:
So there are two variables in the equation, 't', and 'x':
t - time taken to complete the exam
x - number of questions on the exam
