If we define a day as 24 hours, the minute hand moves around the clock face once an hour. 24 times.

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.

All 3 hands overlap 24 times a day.

Overlap happens once 12/11 hour. So 24÷12/11=22 Then overlap occurs 22 or 21 times a day.

Twenty two each.

Infinitely many. They will not stop overlapping -from time to time - as long as the clock keeps on working.

22 times

Eleven.

23 times in all.Note that from 11:00 to 11:59 (am or pm) the hands can never overlap. Thus from 10am to 11:59am, the hands will overlap just once at around 10:54am. The hands will overlap again at exactly 12:00pm (noon). And from 12:01pm to 12:am (midnight) the hands will overlap another 11 times.The following times are the approximate overlapping times.10:54am12:00pm (noon)1:06pm2:11pm3:16pm4:21pm5:27pm6:32pm7:38pm8:43pm9:49pm10:54pm12:00am (midnight).

the hands of a clock are straight 1)when they overlap & face the same direction & 2)when the overlap & face opposite directions this hapns evry 65 min(approx)for each case =>in 1 day 24 hrs=> 24x60 min therefore each case hapns (24x60)/65 times each day................= 22(approx) therefore total # of times = 22+ 22=44
