Find the approximate angle between the hands of a clock on oz when the time is 12:40 am.

Answer 1

Answer:

88.89°

Step-by-step explanation:

36 Hours in a day

=> 18 hours completes a cycle of 360°

=> 1 Hour = 360/18 = 20°

=> 12 Hours = 12 * 20 = 240°

(Hour hand moved in 40 mins  = (40/90)*20 = 8.89°

Hour Hand Moved = 240 + 8.89° = 248.89°

90 minutes  in an Hour

=> 90 minutes = 360°

=> 1 minute = 360/90 = 4°

=> 40 Minutes = 40 * 4 = 160°

Minute Hand Moved = 160°

approximate angle between the hands of a clock = 248.89° - 160

= 88.89°
