Xiao Ming is exercising noodles on an open grass field. He walks as follows: walk straight for a certain distance, then turn 60 degrees clockwise; walk straight for the same length of time, and then turn 60 degrees clockwise; ...and walk back to the original place in this way At that time, I just walked 3 kilometers. May I ask how many meters is the length of the road from the starting point to the first turning?
小明在一块空旷的草地上锻炼面，他按下面走法：直走一段路，然后顺时针转60度；再直走同样长的一段路，然后顺时针60度；…如此走回到原处时，刚好走了3千米．请问他从起点到第一次开始转向的那段路长多少米？
