When the time in the clock is 12.20 the angle between the hands of the clock is xo. find x.?
If the little hand stayed on the 12, the angle would be 120°. Assuming both hands are pointing to 12 o'clock, when the big hand has moved to 20 past (1/3 of the way round) the little hand will have moved 1/3 of the way to the next number (1). So the angle between the hands will be: 1/3 × 360° - 1/3 × 1/12 × 360° = 120° - 10° = 110°.
Two identical clock's one which is 3 seconds slow and the other which is 5 seconds slow give equally precise times?
False. Although both of them are ALWAYS incorrect, the relative error of the first one is smaller. True~ apex
What time between 2 and 3 o' clock do the minute hand and the hour hand overlap each other?
If the hands start off together at midnight, say, then the minute hand must catch up with the hour hand 11 times before they both end up on top of each other again at noon. Hence between one and two o'clock the time when the hands are in the same place is 60/11 = 5.4545... minutes past the hour, between two and three o'clock 2*60/11 = 10.9090... minutes past the hour and so on. So the time you want is 10.91 minutes past 2 o'clock which, to the nearest second, is 2:10:54.
If Watch 1 gains 1 hour every day and Watch 2 gains 20 minutes if both are set correctly at 900 AM on Monday when both be correct at the same time?
If it is a 12 hour clock then on 9 pm on the Tuesday of the sixth week they will both be correct.
