Peter is taking a math exam. There are three parts in the exam: multiple choices, \textquotesingle fill in the blank\textquotesingle, and short answers. The duration of the exam is $90$ minutes, and Peter has already spent $23$ minutes in the multiple choices questions and $35$ minutes on the \textquotesingle fill in the blank\textquotesingle{} questions. What is the possible time he can spend on the last section (short answers) if he wants to finish the exam on time?
