Mark and Matt signed up to walk in a 5K walk/run race. They predicted it would take them 60 minutes to complete the race. Mark and Matt finished the race in 53 minutes. What is the percent error? Round to the nearest tenth.

Answer 1

To find the percent error, we need to calculate the difference between the predicted time and the actual time, and then divide it by the predicted time, and finally multiply by 100 to get the percentage.

The difference between the predicted time and the actual time is: 60 - 53 = 7 minutes.

So, the percent error is: (7/60) * 100 = 11.7%.

Rounded to the nearest tenth, the percent error is 11.7%. Answer: \boxed{11.7}.
