MATHHHHH HEELLLPPPP?

    How much time has he taken so far?

    How much time is left?

    How many questions are left?

    Divide the remaining time by the number of remaining questions.

    On average, he can't take more than that time to complete each question.

    P.S. Don't forget that a full minutes is 60 seconds (not 100).

    I'd provide more detail if you weren't posting anonymously.
