In June, a runner ran a mile in 7:45. In September, the runner ran a mile in 5:51.

Find the percent of change from June to September. Round to the nearest hundredth of a percent.

Answer: 24.52%

Step-by-step explanation: Convert times into decimals by dividing the seconds by 60. (7:45 = 7.75 | 5:51 = 5.85) Subtract 7.75 and 5.85 which equals 1.9

1.9/7.75 = 0.2451612903

Rounded to 0.2452 = 24.52%

Look at them like ratios then as fractions: 7/45 & 5/51 then convert them into a percent.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            Hope This Helps!
