t takes 60 minutes for the minute hand to make one complete revolution. There are 360 degrees in one complete revolution. That’s leaves 360 degrees/60 minutes or 6 degrees/minute.
Thus six minutes would result in moving 36 degrees!

The Minute hand covers 360° in 60 minutes
⇒ the Minute hand covers 360° in 5 × 12 minutes
⇒ the Minute hand covers 30° in 5 minutes
we know that the angular displacement is the angle subtended by the radii of the sector formed by the minute hand.
⇒ clearly the angle subtended by the minute hand in 5 minutes is 30°
so the angular displacement of the minute hand in 5 minutes is 30°

i think the question should be for 5 minutes.
sorry for the mistake. .i rarely commit a mistake in problems. .i assumed you were asking linear displacement.
I did'nt get that. .pardon me would you clear me again? did i make a mistake again?
Thank you Once again. .
