A road construction team plans to build a road in June (30 days), and it needs to build an average of 40m per day to complete the task. In fact, 250m was built in the first 5 days. Based on this calculation, how many days will the task be completed earlier than the original plan?
某筑路队六月份(30天)计划修筑一条公路，平均每天要修筑40m才能完成任务，实际上前5天就修筑了250m，则这样计算，完成任务比原计划将要提前多少天？
<gadget id="calculator">250 / 5</gadget>
<output>50</output>

<gadget id="calculator">30 / 50</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">40 * (3/5)</gadget>
<output>24</output>

<gadget id="calculator">30 - 24</gadget>
<output>6</output>

<result>6</result>
