Logic Question:
"Burning ropes and measuring time"
Suppose you have a box of matches and ropes of different lengths. EACH rope takes EXACTLY ONE HOUR to burn through.
Using logic, you could use the ropes to measure units of time. For example, to measure 30 minutes, you could light each end of a rope simultaneously. (because the burning ends meet halfway after 30 minutes.)
Question: How could you measure 45 minutes?
