Puzzle of the Day - 30th May 2019

Before sleeping Ken realised that he had to complete a novel to be discussed in his English class the next day. So, he decided to read that novel. When he started to read the novel, the lights went off and it was around 2 in the night. Ken lighted 2 candles of equal length but one is thicker than the other. The thick candle is supposed to last six hours and the thin one three hours. When he finally went to sleep, the thick candle was twice as long as the thin one.

Can you determine how long did Ken read in candle light?
