Given,

Hour Hand Moves 20°.

To Find,

Solution,

The hour hand moves 30° in every 1 hour

Thus if hour hand moves 20° ⇒ (20/30)×60 = 40 minutes

⇒ The minute hand has moved for 40 minutes

⇒ The minute hand moves 360° in every 60 minutes

∴  60 → 360

   40 → ?

On cross multiplication, 40×\frac{360}{60} = 240

Henceforth, the minute hand has moves 240° , when the hour hand moves for 20°.
