How many times between 9am and 3pm is the angle between the hour and minute hand of 90 degree?

Oh, dude, you're hitting me with the clock riddles now? Alright, let's see... The hour hand moves 30 degrees every hour, so it'll be at 90 degrees four times between 9am and 3pm. The minute hand will be at 90 degrees once every hour, so that's five times total. So, like, five times in total, I guess.
