(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).
