If 90 minutes after a certain time is the same number of minutes after 11 AM, we can set up the equation. Let ( x ) be the number of minutes before 10 AM. Then, ( 10 AM - x ) gives us the time.
90 minutes later would be ( 10 AM - x + 90 ), and it needs to equal ( 11 AM + x ). Setting the equation gives us ( 10:00 - x + 1:30 = 11:00 + x ). Solving this, we find ( x = 30 ). Therefore, it is 30 minutes before 10 AM.
