Running Last year, an athlete's average time to run a mile was 6min 13s. This year, the athlete's average time is 6min 5s. What is the percent decrease?

Answer 1

The question pertained to calculating a percent decrease for the running time of an athlete. The difference in time was first found, after which the percentage decrease was calculated resulting in a 2.14 percent improvement.

Step-by-step explanation:

The subject of the question pertains to calculating a percent decrease in an athlete's running time. The percent decrease can be determined by subtracting this year's time from last year's, then dividing by last year's time and multiplying by 100. Hence,

1. Firstly, calculate the difference in time: 6min 13s - 6min 5s = 8 seconds.
2. Convert last year's time to seconds: 6min 13s = 373 seconds.
3. Subsequently, calculate the percentage decrease: (8/373)*100 = 2.14 percent.

Thus, the runner has experienced a 2.14 percent decrease in their mile time which indicates their improvement.
