title: How do you calculate how much faster time X is from time Y in terms of %?
body: <p>We're having a bit of a dispute at my office as to how this question should be interpreted. </p>
  
  <p>**Time 1 = 0.6053 seconds
  Time 2 = 1.3477 seconds</p>
  
  <p>What percentage faster is time1 to time 2?**</p>
  
  <p>I am of the believe that if you have a time of X seconds. X/2 (half as long) is 100% faster. </p>
  
  <p>My solution to this problem is calculated as </p>
  
  <p>(T2/T1)-1 </p>
  
  <p>1.3477/.6053 - 1 = 1.2265</p>
  
  <p>Other people are saying that you should just look at these as numbers and calculate it like </p>
  
  <p>1- (T1/T2)</p>
  
  <p>1- .6053/1.3477 = .5508 </p>
  
  <p>(the answers above are rounded). </p>
