On a map with a scale of 1:30000, a road is measured to be 5 cm long, and it will take 6 days to complete the joint repair by teams A and B. The working efficiency ratio of Team A and Team B is 2:3, what is the working efficiency of Team A?
在比例尺1：30000的地图上，量得一条公路长5厘米，由甲乙两队合修需要6天完成．甲乙两队的工作效率比是2：3，求甲队的工作效率？
