how can you calculate 45 minutes if each candels takes 1 hour to burn.

• First light-up the two ends of the 1st candle and one end of the 2nd candle. When the 1st candle will
  burn out ,then light up the both ends of the 2nd candle (15+30=45)

• Assume there are two candels.
  Place both candels horizontally in opposite direction and light both candels simultaneously. Clearly , in 30 minutes both candle will be half burnt
  
  Now again arrange remaining both 'half' candle in opposite direction and note the time till the flames of both candels meet. They will meet in 15 minutes.
  Hence, 30+15=45 min can be calculated.
