The minute hand when it moves 330° from 11 o'clock, is now at ?
9O'clock
11O'clock
12O'clock
10O'clock
We know,
360degree=60minutes1degree=60360minutesOnmultiplyingby330tobothside330degrees=60360×330minutes330degrees=55minutes
So the minute hand will be at 10O'clock.
Hence option D is the correct answer.
When the minute hand of a clock moves by 120∘, the hour hand moves by 10∘.
The hour hand of a clock is at 9 and the minute hand makes an angle of 90∘ with the hour hand. If the minute hand is ahead of the hour hand, what time is it now?
