To celebrate "New Year's Day", the black and white team decorated the big tree in front of the house with a flower ribbon. If you go around the big tree five times, there will be 5 meters left; if you go around the big tree six times, there will be a difference of 1 meter. Then, how many meters is left to wrap this flower ribbon around the big tree twice?
