A man has two ropes of varying thickness (Those two ropes are not identical, they aren’t the same density nor the same length nor the same width) . Each rope burns in 30 minutes . He actually wants to measure 45 minutes . How can he measure 45 minutes using only these two ropes . He can’t cut the one rope in half because the ropes are non – homogeneous and he can’t be sure how long it will burn .
