	\problem{}
	Suppose we have two strings and a lighter. Each string takes an hour to fully burn. \par
	However, we do not know how fast each part of the string burns:
	half might burn in 1 minute, and the rest could take 59.

	\vspace{2mm}

	How would we measure exactly 45 minutes using these strings?
