Mark and Matthew signed up to walk in a 5k walk/ run race they predict it will take them 60 minutes to complete the race mark and Matthew finished the race in 53 minutes what is the percent error round to the nearest tenth
To calculate the percent error, we need to find the difference between the predicted time (60 minutes) and the actual time (53 minutes), divide it by the predicted time, and then multiply by 100.
Difference = Predicted time - Actual time
Difference = 60 minutes - 53 minutes
Difference = 7 minutes
Percent Error = (Difference / Predicted time) * 100
Percent Error = (7 minutes / 60 minutes) * 100
Percent Error = 11.67%
Rounding to the nearest tenth, the percent error is 11.7%.
