A certain construction site uses the same truck to transport away a pile of soil. If it takes 180 trucks a day, it takes 40 days, and it needs to be shipped 15 days in advance. How many trucks do you need to transport every day? (Solve with ratio)
某工地用同样的车运走一堆土，如果每天运180车，需40天，要提前15天运完，每天要运多少车？(用比例解)

<gadget id="calculator">40 - 15</gadget>
<output>25</output>

<gadget id="calculator">7_200 / 25</gadget>
<output>288</output>

<result>288</result>
