Question

If we add the number of revolutions made by the hour hand and the minute hand in a day (24 Hrs), what will we get?​

Answer 1

The number of revolutions made by the hour and minute had in total in a day would be 26 revolutions.

• A clock is known to be a device that tracks and measures time. There are 3 hands that a clock has to indicate the hour, the minutes as well as the seconds called as the hour hand, minute hand and the second hand respectively.
• A revolution is said to be a complete traversal of the entire circular path of the clock, that is, covering a total angle of 360° throughout is known as one revolution or one round.
• Thus, the number of revolutions taken by the hour and the minute hand is to be calculated.
• An hour hand is one that shows us which hour of the day it is and keeps track of the hours of the day.
• We know that a clock has 12 divisions in total and each number is 5 markings apart. Thus, each number from 1-12 indicate the hours in the clock.
• When the hour hand travels from one division to another it means that one hour is completed.
• Since, there are 12 divisions total and the hour hand travels 5 markings per hour (1 division), for 12 divisions the clock covers an entire revolution so in 12 hours the hour hand would have travelled 1 revolution.

So, we have:

                                             12 hours=1 revolution

                                             24 hours=x revolutions

                                             $x=\frac{24\times 1}{12}$

                                              $\implies x=\frac{24}{12}=2$

• Hence, 2  revolutions are covered in 24 hours, that is, 1 day by the hour hand of the clock.
• Similarly, the minute hand traverses the complete circle in the duration where the hour hand moves from one division to another.
• This means that when the hour hand moves from one division to the next, in the same time duration the minute hand completes an entire revolution.
• Since, there are 12 divisions on a clock indicating 12 hours the minute hand would cover one revolution per hour. So for 12 hours it will cover 12 revolutions correspondingly.
• Thus, for 24 hours of the day the minute hand would have travelled 24 revolutions in total.
• Hence, the sum of the revolutions made by the hour and the minute hand will be given as:
• Sum of the revolutions= Revolutions of hour hand + Revolutions of minute hand

                                         Sum of revolutions= 2+24

                                      ⇒Sum of revolutions= 26 revolutions

• Thus, this is the total number of revolutions taken by the hour and minute hand of the clock in 1 day

Answer 2

If we add the number of revolutions made by the hour hand and the minute hand in a day (24 hours), we get 26 revolutions.

• A device that tracks and measures time is known as a clock.
• The hour hand, minute hand, and second hand are the three hands on a clock that are used to display the hour, minutes, and seconds, respectively.
• A revolution is defined as the full circumference of the clock's circular route, or as the circumference of one round, which covers an angle of 360°.
• An hour hand keeps track of the hours of the day and lets us know what hour it is.
• An minute hand keeps track of the minutes of the hour and lets us know which minute it is.
• There are 12 hour markings in the clock. Since there are 24 hours a day, the hour hand makes 24/12 = 2 revolutions.
• There are 60 minute markings in the clock. Since there are 24 hours a day, the minute hand makes = 24 revolutions.
• Hence, the total number of revolutions made by the hour hand and the minute hand is 26 revolutions.
