A road repairing team planned to build a section of road, but actually built 300 meters more (1/12) of this section of road every day, so it just finished in 8 days. How many kilometers is this road in total?
一个修路队计划修一段路，实际每天修这段路的(1/12)还多300米，这样8天刚好修完．这段路共有多少千米？
<gadget id="calculator">300 / 1_000</gadget>
<output>3/10 = around 0.3</output>

<gadget id="calculator">1 / 8</gadget>
<output>1/8 = around 0.125</output>

<gadget id="calculator">1 / 12</gadget>
<output>1/12 = around 0.083333</output>

<gadget id="calculator">(1/8) - (1/12)</gadget>
<output>1/24 = around 0.041667</output>

<gadget id="calculator">(3/10) / (1/24)</gadget>
<output>36/5 = around 7.2</output>

<result>36/5 = around 7.2</result>
