(Use the equation to solve) To build a road, the full length (1/3) was built on the first day, and the full length (1/4) was built on the second day. The first day was 120 meters longer than the second day. This road How many meters in total?
(用方程解答)修一条路，第一天修了全长的(1/3)，第二天修了全长的(1/4)，第一天比第二天多修120米，这条路一共多少米？
<gadget id="calculator">1 / 3</gadget>
<output>1/3 = around 0.333333</output>

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

<gadget id="calculator">(1/3) - (1/4)</gadget>
<output>1/12 = around 0.083333</output>

<gadget id="calculator">120 / (1/12)</gadget>
<output>1_440</output>

<result>1_440</result>
