Find the angle traced by the hour hand of a correct clock between 7 o'clock and 3 o'clock.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 240°
The hour hand goes once round the dial, 360° in 12 hours, so it turns \(\frac{360^\circ}{12}=30^\circ\) every hour. A correct clock moves only forward (clockwise).
From 7 o’clock to 3 o’clock is 8 hours (7 to 12 is 5 hours, 12 to 3 is 3 more)
Angle traced \(=8\times30^\circ=\) 240°
