find the percent of change from June to September in the time to run a mile (the June time is 7:45 and the September time is 5:5

Leviafan [203]

Answer:

74% change

Step-by-step explanation:

Percentage is the fraction between two values usually the obtained value against the total obtainable value and multiply by 100.

% change = (value in September / value in july) * 100

% change = (5.51 / 7.45) * 100

% change = 0.7395 * 100

% change = 74%
