First correct answer will get Brainliest - due today! (last time) Dora has three candles, which will burn for 3, 4 and 5 hours, respectively. If she wants to keep two candles burning at all times, what is the greatest number of hours she can burn the candles? (Dora has a clock that she can use to time the candles.)

5 hours at most. because she could burn the 5 hour and 4 hour at the same time, then when the 4 hour runs out she could start the 3 hour which will be able to cover the next hour until the 5 hour runs out, with only the 3 hours left with 2 hours remaining in which it will burn by itself. the answer is 5 hours.
