The engineering team repairs a 2.4-kilometer-long highway. On the first day, it builds 1/3 of the full length, and on the second day, it repairs 40% of the total length. How many kilometers more will be repaired on the second day than on the first day?
工程队修一条长2.4千米的公路，第一天修全长的(1/3)，第二天修全长的40%，第二天比第一天多修多少千米？

<output>2/5 = around 0.4</output>

<gadget id="calculator">1 / 3</gadget>
<output>1/3 = around 0.333333</output>

<gadget id="calculator">(2/5) - (1/3)</gadget>
<output>1/15 = around 0.066667</output>

<gadget id="calculator">24 * (1/15)</gadget>
<output>8/5 = around 1.6</output>

<result>8/5 = around 1.6</result>
