(20 14? Nanning simulation) In a summer camp, Xiaoming started from Camp A and arrived at C, which is 60 northeast of A, and he walked in a straight line first.

B is to the east of A, and C is to the northeast of A? 60 direction,

∴∠BAC=90 -60 =30，

∫C is 30 degrees east of the north of B,

∴∠ABC=90 +30 = 120，

∴∠c= 180-∠BAC-∠ABC = 180-30- 120 = 30，

∴∠BAC=∠C，

∴BC=AB=200m.

So the answer is: 200.
