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.(1 point)
To calculate the percent error, we need to find the absolute difference between the predicted time and the actual time, and then divide it by the predicted time and multiply by 100.
Absolute difference = 60 minutes - 53 minutes = 7 minutes
Percent error = (7 minutes / 60 minutes) * 100% = 11.7%
Therefore, the percent error is 11.7%.
To find the percent error, we need to compare the predicted time to the actual time.
Step 1: Subtract the predicted time from the actual time:
53 minutes - 60 minutes = -7 minutes
Step 2: Take the absolute value of the difference:
|-7 minutes| = 7 minutes
Step 3: Divide the absolute difference by the predicted time and multiply by 100 to get the percent error:
(7 minutes / 60 minutes) x 100 = 11.67
Rounded to the nearest tenth, the percent error is 11.7.
To calculate the percent error, we need to find the difference between the predicted time and the actual time, and then divide it by the predicted time. Here's how you can do it step by step:
1. Calculate the difference between the predicted time and the actual time:
Actual time = 53 minutes
Predicted time = 60 minutes
Difference = Actual time - Predicted time
= 53 - 60
= -7 minutes
2. Divide the difference by the predicted time:
Percent error = (Difference / Predicted time) * 100
Percent error = (-7 / 60) * 100
= -11.67
3. Round the percent error to the nearest tenth:
Rounded percent error = -11.7
Therefore, the percent error is approximately -11.7%.
