The engineering team built a section of expressway, originally planned to build 0.4 kilometers per day, and completed the task in 60 days. Due to the increase of machinery and equipment, the actual daily repairs are 25% more than the original plan. How many days are actually required to complete the task? (Solve with ratio)
工程队修建一段高速公路，原计划每天修0.4千米，60天完成任务．由于增加了机器设备，实际每天比原计划多修25%，实际多少天完成任务？(用比例解)
<gadget id="calculator">0.4 * 60</gadget>
<output>24</output>

<gadget id="calculator">25 / 100</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">1 + (1/4)</gadget>
<output>5/4 = around 1.25</output>

<gadget id="calculator">0.4 * (5/4)</gadget>
<output>0.5</output>

<gadget id="calculator">24 / 0.5</gadget>
<output>48</output>

<result>48</result>
