Two candles=8 hours=8*60=480 minutes
4 inch is 4/12 of a candle, 4/12 of 4 hours=16/12=4/3 hours=80 minutes
so the total minutes are 480+80=560

Answer:

480+80=560

If a colored candle and a white candle are burned at the same time for an hour, then the colored candle will burn faster, because it has more chemicals than the white candle.
