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.

How many times does the hour hand go round the clock in one week?
Every day the hour had travels once round the clock in the morning and one round the clock in the afternoon, so it travels twice round the clock in 1 day. There are 7 days in a week, thus the hour hand travels 7 x 2 = 14 times round the clock in a week.
