Study Notes on Clock

By Gaurav Mohanty|Updated : December 23rd, 2021

The analog clock typically has three hands; a smaller one called the hour hand, a larger one called the minute hand and a slender long hand called the second hand. The dial of the clock is a circle whose circumference is divided into 60 equal parts. Each part is called a minute space.

The analog clock typically has three hands; a smaller one called the hour hand, a larger one called the minute hand and a slender long hand called the second hand. The dial of the clock is a circle whose circumference is divided into 60 equal parts. Each part is called a minute space.

For one complete revolution of the second hand, the minute hand covers one-minute space, and the time is taken for this is called a minute. For one complete revolution of the minute hand, the hour hand covers five-minute spaces, and the time taken for this is called an hour.

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

Important Pointers to master clock problems

  • At any given point of time, the hour hand and the minute hand make an angle between 0° and 180° with each other.
  • The angle covered by the 60-minute spaces on the face of the dial is 6°.
  • The minute hand covers 6° per minute and the hour hand covers 30° per hour or per minute.
  • In 60 minutes, the minute hand gains 55 minutes on the hour hand.
  • In any one hour, the hour hand and the minute hand coincide exactly once.
  • When the hour hand and the minute hand are at right angles, they are 15-minute spaces apart.
  • When the hour hand and the minute hand are opposite each other, they are 30-minute spaces apart.
  • The angle F between the hour hand and minute hand of the clock at any given point of time can be calculated using the given formula where,
    M = minutes
    H = hours
