Kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.

%error = (calculated value - experiemental value) / calculated * 100%

%error = (95-80) / 95*100%=15/95 * 100% = 15.79 ≈ 16% error

Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
