During the summer vacation, Lingling borrowed a book of "Harry Potter". The original plan was to read an average of 26 pages a day and finish it in 10 days. Because it looks better, I actually read 14 more pages a day on average. How many days did I actually finish reading it?
暑假中，玲玲借到一本《哈利•波特》的书，原计划平均每天看26页，10天看完．由于比较好看，实际平均每天多看14页，实际几天看完？
<gadget id="calculator">26 + 14</gadget>
<output>40</output>

<gadget id="calculator">10 / 40</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">26 * (1/4)</gadget>
<output>13/2 = around 6.5</output>

<result>13/2 = around 6.5</result>
