Question

where will the hand of a clock stop if kavya starts from 5 and make 3/4 of a rotation anti clock wise?​

Answer 1

Answer:

Answer: In one complete revolution the clock hand returns back to the same position. So, if it starts at 12 then it would again stop at 12, if it starts at 2 it would again stop at 2 and if it starts at 5 it would again stop at 5.

Let's understand the concept of turning clockwise and anti-clockwise.

Explanation:

In one complete revolution clock hand moves 360° or 12 hours.

Hence, the clock hand would eventually come back to the same point in all the cases.

Turning of clock hand clockwise and anti clockwise

Therefore, if it starts at 12 then it would again stop at 12, if it starts at 2 it would again stop at 2 and if it starts at 5 it would again stop at 5.

Answer 2

Question :- where will the hand of a clock stop if kavya starts from 5 and make 3/4 of a rotation anti clock wise ?

Solution :-

we know that,

• 1 rotation = 360° .

so,

→ (3/4) of rotation = (3/4) * 360° = 270° .

then,

→ 5 + 270° (anticlockwise)

→ 5 + {(180° + 90°)anticlockwise}

→ (5 + 180° anticlockwise) + 90° anticlockwise

→ 11 (opposite) + 90° anticlockwise

→ 11 + 90° anticlockwise

→ 11 + 3*30° anticlockwise

→ 11 - 3

→ 8 (Ans.)

Hence, the hand of a clock stop will stop at 8 .
