speedup computation?

let's say i have an algorithm A run on two machines X and Y. So below is the result

   Machine    Elapsed time(sec)
      X            20
      Y            10

how do you express the speedup? ... thanks!

20 / 10 = 2, subtract 1 (base), multiply by 100 and you have a 100% speed-up on machine X.
