It usually only takes 20 minutes for Xiaoqiang to go from home to school by bicycle. Because there were 2 kilometers of road construction on the way, I had to push the cart and walk. The walking speed was only 1/3 of that of a bicycle. As a result, it took 36 minutes to reach the school. How many kilometers is it from Xiaoqiang's home to the school?
小强骑自行车从家到学校去，平常只用20分钟．由于途中有2千米正在修路，只好推车步行，步行速度只有骑车的(1/3)，结果用了36分钟才到学校．小强家到学校有多少千米？
