Planet A has 36 hours in a day,90 minutes in an hour and 60 seconds in a minute. It has same pattern as our watch. Find angle between hour hand and minute hand at 9:40 in the morning?

• clock has 18 hours in one rotation
  1 rotation =360
  1 hour=360/18=20 degrees
  1 hour=90 minutes
  1 minute=2/9 degrees
  and
  90 minutes=360 degrees
  1 minute=4 min
  now formula=((hours*20)+(minutes*2/90))-(minutes*4)
  ((9*20)+(40*2/9))-(40*4)
  =28.9
