On the planet Oz, there are 8 days in a week- Sunday to Saturday and another day called Oz day. There are 36 hours in a day and each hour has 90 min while each minute has 60 sec. As on earth, the hour hand covers the dial twice every day. Find the approximate angle between the hands of a clock on Oz when the time is 9:40 am.

• At Exact 9:40 , min hand will make an angle of 160 deg with second hand.
  At Exact 9:40 , Hour hand will make an angle of approx 189 deg with second hand.
  
  Angle between hr and minute hand = 29 deg.

• As, we have 36 hour in a day. So, the dial has 18 hours(36/2=18) to cover daily twice. Now a dial has 360*. So, in one hour hand moves 360/18=20*.
  So, for 12 hour hand moves 9x20=180*.
  Now for minutes, hour hand moves 20/90
  for 40 minutes it moves 20/90x40=8.88*
  So for 12:40 hour hand moves 180+8.88=188.88*.
  
  Now, minute hand moves 90 minutes to complete one hour.
  for one minute it moves 360/90=4*
  for 40 minutes it moves 4x40=160*
  
  So, the angle between hour hand and minute hand is 188.88-160=28.88
  
  The ans is 29*
