How many degrees will the hour hand move, in the time within which the minute hand moves 240°?

20°

The correct answer is Option (1) → 20°

The minute hand moves 360° in 60 minutes, i.e. 6° per minute.

So, time taken to move 240°
$=\frac{240}{6} = 40$ minutes.

The hour hand moves 30° in 60 minutes, i.e. 0.5° per minute.

In 40 minutes, hour hand moves
$=40 \times 0.5 = 20°$
