Question

Jillian calculates that see will take 95 minutes to run 7 miles. She runs the distance in 80 minutes. What is Jillian’s percent error? ​

Answer 1

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.
