How many times do your eyes blink every 30 seconds?
Well on average people blink once every ten seconds so three times in 30 seconds :)
How many times a day do the hour and minute hands on a clock line up exactly with each other?
Once every hour, so 24 times in a 24-hour day.
What comes only once in a year but twice in every month and four times in every week?
The letter "E."
How many times does the minute hand move around the clock face in one day?
If we define a day as 24 hours, the minute hand moves around the clock face once an hour. 24 times.
How many times a day does the number 1 appear on a 24 hour clock?
An hour has 60 min. Assuming the clock has only the hour and minute displayed, every hour 1 would appear at 1, 11,12,13,14,15,16,17,18,19,10,21,31,41,51. Counting 11 as once there are 15 1s in an hour. In the 24 hours, only 0,2,3,4,5,6,7,8,9,22,23 have no 1 s in them. Therefore 1 aooears 165 times in those times. As for hours 1,10,11,12,13,14,15,16,17,18,19,21, there is always a 1 in the clock. This makes 1 appear 12*60 times which is 720 times. Therefore in total, 1 appears 885 times in a digital 24 hour clock.
