Question

At exact 11:00 the hour hand is at number 11 on the clock .How many degrees would this hour hand move at 11:20?
give me the answer ​

Answer 1

Answer:

140 degree

Explanation:

At 11:20, the minute hand would have effectively travelled for 20 minutes covering (20 * 6 = 120°) after completing eleven full revolutions in eleven hours with net ZERO displacement from reference point.

The Hour hand would have travelled for 60*11 + 20 = 680 minutes. It covers an angle of 680 x 0.5 = 340°

The angle between the two hands now is 340°-120°=220°

But, we have to consider only the reflex angle, i.e, 360 - 220 = 140°
