Answer:

  18% better

Step-by-step explanation:

The percentage improvement is computed as ...

  percent change = ((new value) -(old value))/(old value) × 100%

  = ((2:44 -3:20)/(3:20)) × 100%

  = (164 -200)/200 × 100%

  = -36/200 × 100%

  = -18%

Sarah's time has improved (decreased) by 18%.
