An engineering team repaired a canal. On the first day, they repaired (3/10) kilometers, and on the second day they repaired (1/12) more than the first day. How many kilometers were repaired in two days?
某工程队修水渠，第一天修了(3/10)千米，第二天比第一天多修(1/12)，两天共修了多少千米？
<gadget id="calculator">3 / 10</gadget>
<output>3/10 = around 0.3</output>

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

<gadget id="calculator">1 + (1/12)</gadget>
<output>13/12 = around 1.083333</output>

<gadget id="calculator">(3/10) * (13/12)</gadget>
<output>13/40 = around 0.325</output>

<gadget id="calculator">(13/40) + (3/10)</gadget>
<output>5/8 = around 0.625</output>

<result>5/8 = around 0.625</result>
