How many times a day do the hands of a clock form a perfect 90-degree angle?
only does a perfect 90-degree angle twice – 3 and 9 o’clock almost said four times because of 3:30 and 9:30 but the hour hand is between numbers when it’s half past the hour… and on a digital clock, none. Crap, I just remembered 3 and 9 happen twice a day, which would make it 4 times… except I just remembered times such as 4:05, 5:10, 6:17 – Nevermind, I quit, the guy who answered 48 is correct.
