Two teams, A and B, are building a road. It will take 12 days for A to work alone, and 10 days for B to complete it alone. Now team A will practice for a few days first, and the rest will be done by B alone. As a result, A worked 1 day longer than B when it was completed. How many days did Team B spend on repairing?
