An accurate clock shows the time as 3.00.After hour hand as moves 135(deg),the time would be.
Hour hand covers an angle of 360 in 12 hours.
Time taken to cover an angle of 135 degree = (12 x 135)/360 =4.5 hr
Required time = 3 + 4.5 = 7.5 = 7:30
Hope this helps :)
The hour hand covers an angle of 360° in 12 hours
∴Time taken to cover an angle of 135° = 12/360 =4.5 h
∴ Required time = 3.00 + 4.5 = 7.5 = 7:30
Hence the time would be 7:30 after the hour hand moves 135° because it will cover 4½ hours in those 135° after 3:00.
