Starting with the hour hand. And considering 6 and 12 hand to be also a right angle one. The hour hand will be at right angles 2 times .
The minute hand covers 4 right angles in an hour. There are a total of six hours. So the minute hand will have (4*6)= 24 times.
The second hand covers it 4 times in a minute. So in six hours it will be.
(4*60*60) which is 14400
So the total number of times that a hand is at right angles during these six hours is 14400+24+2
