A candle that burns out completely in one hour costs \(60\) pence and a candle that lasts for
\(11\) minutes costs \(11\) pence. For some reasons which he
doesn’t want to explain to the seller, Mr. Fawkes wants to measure
exactly \(1\) minute with some of these
candles. Can he manage to do that if he has only \(1\) pound and \(50\) pence to spend on the candles?
Mr. Fawkes can only measure the whole interval with each of the candles.
He is not guaranteed that any of the candles burns uniformly, so he
cannot divide it into two parts. He cannot make it burn faster by
igniting them from both ends, but he can extinguish a candle and light
it up again later.
