The floor plan of the playground is drawn at a scale of 1:3000. It is known that the actual length of the playground is 150 meters. An ant in the picture takes 5 seconds to walk the entire length of the playground. How many meters does the ant travel on average per second?
操场的平面图是按1：3000绘制的，己知操场实际全长150米，图上一只蚂蚁用了5秒钟走完了操场的全长，求这只蚂蚁平均每秒行多少米？

<output>1/3_000 = around 0.000333</output>

<gadget id="calculator">(1/3_000) / 5 / 100</gadget>
<output>1/1_500_000 = around 0.000001</output>

<gadget id="calculator">150 * 100 * (1/1_500_000)</gadget>
<output>1/100 = around 0.01</output>

<result>1/100 = around 0.01</result>
