1）由题目角ABC为30°,BC=6,则AC=2√3,A‘C=2√3
由于A‘C=AC,且∠A=60°,故A'AC为正三角形,∠A'CA=60°,则∠A'CD=30°,则有△A'BD=△A'DC,A'C=A'B=AC=1/2AB
（2）A'C=2√3,则有A'D=√3,DC=3,面积是3√3/2

设所求x千米,则原来速度：x/3千米/小时
5.6/[(x/3)*(3/4)]-5.6/(x/3)=12/60
解得x=28千米

丽萍我爱你
Liping,I love you.
Dear,Liping,I love you.

这种题,解法就是用称得的质量减去2倍游码的示数（自己去想为什么）,
这个题上,游码的示数是1g,所以实际质量是21-2*1=19克.

18/(18+2)=90%
