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.
First, we need to calculate the actual time it took Mark and Matthew to complete the race, based on their prediction of 60 minutes.
The percent error is calculated using the formula:
(error/actual value) x 100.
The actual time it took Mark and Matthew to complete the race is 53 minutes.
To find the percent error, we need to calculate the difference between their prediction and the actual time, and then divide that by the actual value:
Error = Actual value - Predicted value
= 53 - 60
= -7
Now we can calculate the percent error:
(error/actual value) x 100
= (-7/60) x 100
= -11.7
Since we are asked to round to the nearest tenth, the percent error is approximately -11.7%.
Therefore, the percent error is approximately -11.7%.

To find the percent error, you need to calculate the difference between the predicted time and the actual time, then divide it by the predicted time, and finally multiply by 100.
First, subtract the actual time (53 minutes) from the predicted time (60 minutes):
60 - 53 = 7 minutes
Next, divide the difference by the predicted time:
7 / 60 = 0.1167
Finally, multiply the result by 100 to find the percent:
0.1167 x 100 = 11.67
Rounded to the nearest tenth, the percent error is approximately 11.7%.
To calculate the percent error, we can use the formula:
Percent Error = (|Measured Value - Predicted Value| / Predicted Value) * 100
In this case, the measured value is 53 minutes, and the predicted value is 60 minutes.
Step 1: Calculate the difference between the measured value and predicted value:
|53 - 60| = 7
Step 2: Divide the difference by the predicted value:
7 / 60 = 0.1167
Step 3: Multiply the result by 100 to get the percent:
0.1167 * 100 = 11.67
Therefore, the percent error is approximately 11.7%.
