HELP REALLY QUICK 20 POINTS!
BartSMP [9]

Answer:

18%

Step-by-step explanation:

To calculate percentage improvement use

percentage improvement = \frac{improvement}{original} × 100%

Change time to seconds

3 minutes 20 sec = (3 × 60) + 20 = 200 seconds

2 minutes 44 seconds = (2 × 60) + 44 = 164 seconds

improvement time = 200 - 164 = 36 seconds, hence

percentage improvement = \frac{36}{200} × 100% = 18%
