A quarter of the clock is 3 hours. a full revolution is 12 hours. 3 quarters means 9 hours which means if we start the 3/4 revolution from 6 it would finish at 3. so it is the correct answer

Where will the hand of a clock stop if it starts at 6 and makes 3/4 of...
Explanation:
To solve this problem, we need to understand how the hands of a clock move and how much each hand covers in a given time.
- A clock has two hands, the hour hand and the minute hand.
- The hour hand moves 12 times slower than the minute hand.
- In one revolution, the minute hand covers 360 degrees, while the hour hand covers 30 degrees.
If the hand of a clock starts at 6 and makes 3/4 of a revolution clockwise, we need to find out where it will stop.
Step 1: Calculate the total degrees covered by the minute hand:
- In one revolution, the minute hand covers 360 degrees.
- In 3/4 of a revolution, the minute hand will cover (3/4) * 360 = 270 degrees.
Step 2: Calculate the total degrees covered by the hour hand:
- In one revolution, the hour hand covers 30 degrees.
- In 3/4 of a revolution, the hour hand will cover (3/4) * 30 = 22.5 degrees.
Step 3: Calculate the final position of the hour hand:
- The hour hand starts at 6, which is equivalent to 180 degrees.
- To find the final position, we add the degrees covered by the hour hand: 180 + 22.5 = 202.5 degrees.
Step 4: Determine the corresponding number on the clock:
- To find the number on the clock that corresponds to 202.5 degrees, we need to divide 202.5 by 30 (since each number on the clock corresponds to 30 degrees).
- 202.5 / 30 = 6.75
- The number 6.75 corresponds to the number 3 on the clock.
Therefore, the hand of the clock will stop at the number 3.
To solve this problem, we need to understand how the hands of a clock move and how much each hand covers in a given time.
- A clock has two hands, the hour hand and the minute hand.
- The hour hand moves 12 times slower than the minute hand.
- In one revolution, the minute hand covers 360 degrees, while the hour hand covers 30 degrees.

- 202.5 / 30 = 6.75
- The number 6.75 corresponds to the number 3 on the clock.
Therefore, the hand of the clock will stop at the number 3.
