A middle school's 7th-grade literary and arts representative team took a bus to a county middle school 21 kilometers away from their school to participate in a competition. When they reached place A, the driver received a phone call from the school: "Hello, is this Mr. Zhang?" "Yes, it's me." "Please return immediately to pick up the 8th-grade sports representative team and take them to the county middle school, and let the 7th-grade team walk there." After resting for 10 minutes, the 7th-grade team started walking, and the bus did not stop on its return journey. When the bus arrived at the county middle school with the 8th-grade team, the 7th-grade team also arrived at the same time. It is known that the walking speed is 4 kilometers per hour, and the bus speed is 60 kilometers per hour. Find the distance from the school to place A and the distance walked by the 7th-grade representative team.
