Ropes? Fires? Timers? What is this? An episode of Fear Factor? Nope, it’s your weekly Rompecabeza. Can you figure it out?

You have two ropes of equal length and made from the exact same material that take exactly one hour to burn if lit on one end. 

Without cutting either rope, how can you burn both completely in exactly 45 minutes?

ANSWER TO LAST WEEK’S PUZZLE

Two fathers and two sons sat down to eat some cheeseburgers. They ate exactly three cheeseburgers, and each of them had one. We asked you to explain.
