title: Time spent to sort 10^7 records with insertion sort
body: <p>I am stuck with my revision for the upcoming test.</p>
  
  <p>The question says:</p>
  
  <blockquote>
    <p>An implementation of insertion sort spent 1 second to sort a list of 10^6 records. How many seconds it will spend to sort 10^7 records?</p>
  </blockquote>
  
  <p>By using </p>
  
  <pre><code>T(X)/T(1) = 10^7/10^6 
  </code></pre>
  
  <p>I thought the answer was 10 seconds but the actual answer says it's 100 seconds.</p>
  
  <p>Can someone please help me out? </p>
