Measure time by burning ropes

Write e-mail

You are given 2 different ropes, each having varying thickness through the length. Despite the two ropes being different, it is given that they both burn for exactly 30 seconds each. You have to measure a time period of 45 seconds using these two ropes. Remember, cutting the rope into half doesn't mean that the half will burn in 15 seconds since the thickness is not uniform.
