Mark and Matthew signed up to walk in a 5k walk/run race they predicted it will take them 60 minutes to complete the race Mark and Matthew finish the race and 53 minutes what is the percentage error round to the nearest tenth
To calculate the percentage error, we need to find the difference between the predicted time and the actual time and then divide it by the predicted time. Finally, we multiply the result by 100 to find the percentage.
The difference between the predicted time and the actual time is: 60 minutes - 53 minutes = 7 minutes
The percentage error is then: (7 minutes / 60 minutes) * 100 = 11.7%
Rounded to the nearest tenth, the percentage error is approximately 11.7%.
