Hi Shifus, could you kindly help with the following?

I got 4 hrs 17 1/7mins. Could you advise if I’m correct?

Thank you in advance.

Two candles of equal length are lit at the same time. Candle A takes 10 hours to burn down while Candle B takes 5 hours to burn down. Find the time taken, in hours and minutes, to burn both candles such that Candle A is exactly 4 times as long as Candle B.
