The angular distance covered by the minute hand in 1 Hr 20 minutes is :
Answer & explanation
Correct answer: option 2
Movement of minute hand in 60 minutes = 360 degrees
So, the angular speed of the minute hand = 6 degrees per minute
In 60 minutes / 1 hour, angular distance cover by minute hand = 6 × 60 = 360 degrees
In 20 minutes, angular distance cover by minute hand = 6 × 20 = 120 degrees
So, the angular distance covered by the minute hand in 1 hour 20 minutes
= 360 + 120
= 480 degrees
