A marathon runner aims for a time of 3 hours but finishes in 3 hours and 15 minutes. Calculate the percentage error in the runner's target time. If another runner finishes in 2 hours and 55 minutes, what is the percentage difference in finishing times between the two runners?

Please give me the solution and answer

Convert the target time of 3 hours to minutes: 3 hours = 3 * 60 = 180 minutes2 Convert the actual time of 3 hours and 15 minutes to minutes: 3 hours and 15 minutes = (3 * 60) + 15 = 195 minutes3 Calculate the absolute error: |195 - 180| = 15 minutes4 Calculate the percentage error: (15 / 180) * 100% = 8.33%5 Convert the time of the second runner to minutes: 2 hours and 55 minutes = (2 * 60) + 55 = 175 minutes6 Calculate the absolute difference in finishing times: |195 - 175| = 20 minutes7 Calculate the percentage difference in finishing times: (20 / 195) * 100% = 10.26%
