(2) The minute hand rotates 4× 30 = 120,
Rotate clockwise 2060× 30 =10;
So the answer is: (1)120; (2) 120 , 10 ;
(3) Leave at 8: 00 x and return to school at 2: 00 p.m..
Then (12-1) × x60× 30 = 8× 30,
X=480 1 1≈44,
( 12- 1)×y60-2×30 = 180,
The solution is y=480 1 1≈44,
Therefore, * * * takes six hours (leaving at 8: 44 and returning to school at 2: 44).
