Two candles of equal length are lit at the same time. Candle A takes 10 hours to burn out completely while candle B takes 7 hours to burn out completely. Assuming that each candle burns at a constant rate, find the time taken for the candles to burn till the length of candle A is 4 times longer than candle B. Give your answer to the nearest minute.
