The engineering team built a road, and the ratio of the number of meters repaired to the total length in the first half of the month was 1:5. If another 360 meters are repaired, just half of the road will be repaired. How long is this road in meters?
工程队修一条路，上半月修好的米数与全长的比是1：5．如果再修360米，就正好修了这条路的一半．这条路全长多少米？

<output>1/2 = around 0.5</output>

<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">(1/2) - (1/5)</gadget>
<output>3/10 = around 0.3</output>

<gadget id="calculator">360 / (3/10)</gadget>
<output>1_200</output>

<result>1_200</result>
