Question

The minor angle between the hours hand and minutes hand of a clock was observed at 8:48 am. The minimum duration, in minutes, after 8.48 am when this angle increases by 50% is

Accepted Answer

24 11 \frac{24}{11} 11 24 ​. The given time is 8:48 AM. Angle made by hours hand w.r.t 12 is 8 * 30 (30 degrees in 1 hour) + 0.5 * 48 (0.5 degree in 1 minute) = 240 + 24 = 264 degrees. Angle made by minutes hands w.r.t 12 is 48 * 6 = 288 degrees. => The angle between them is 288 - 264 = 24 degrees. This should further increa
