修路队修一条公路，计划每天修105米，450天完成，如果要提前30天完成，那么实际每天要修多少米？(用方程解)
<gadget id="calculator">105 * 450</gadget>
<output>47_250</output>

<gadget id="calculator">450 - 30</gadget>
<output>420</output>

<gadget id="calculator">47_250 / 420</gadget>
<output>225/2 = around 112.5</output>

<result>225/2 = around 112.5</result>
