when the hour hand will be move to 135 degrees forward, the time would be 7 hours 30 minutes.
The hour hand of a clock covers a rotation in 12 hours.
That means 360° is covered by the hour hand in 12 hours.
So, in 1 hour, the hour hand covers = (360°/12) = 30°.
Thus, for 30° forward, the hour hand moves 1 hour.
By unitary methord, for 1° forward, the hour hand moves (1/30) hours.
So, for 135° forward, the hour hand moves (135/30) hours = 4.5 hours = 4 hours 30 minutes.
If the starting time was 3hours 00 minutes, so time after 4 hours 30 minutes would be :
(3 : 00 + 4 : 30) = 7 hours 30 minutes.
Time would be 7 hours 30 minutes.
