The engineering team builds a road. On the first day, it builds 30 meters. On the second day, it repairs 10% more than the first day. After two days of repairing, there is still a full length (1/8) from the midpoint. How many meters is the total length of this road?
工程队修一条路，第一天修了30米，第二天比第一天多修10%，修了两天后离中点还有全长的(1/8)，这条路全长多少米？

<output>1/10 = around 0.1</output>

<gadget id="calculator">30 * (1/10)</gadget>
<output>3</output>

<gadget id="calculator">30 + 30 + 3</gadget>
<output>63</output>

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

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

<gadget id="calculator">(1/2) - (1/8)</gadget>
<output>3/8 = around 0.375</output>

<gadget id="calculator">63 / (3/8)</gadget>
<output>168</output>

<result>168</result>
