Mia and Robert signed up to walk in a 5K walk/run race. They predict it will take them 60 minutes to complete the race. Mia and Robert finish the race in 53 minutes. What is the percent error?
Round to the nearest tenth.
Percent Error formula = ��������� − ������������ × 100\frac{estimated\ -\ actual}{actual}\ \times \ 100
actual
estimated − actual
× 100
First, we need to find the estimated time and the actual time.
The estimated time is given as 60 minutes.
The actual time is given as 53 minutes.
Now, we can calculate the percent error using the formula:
Percent Error = (estimated - actual) / actual * 100
Percent Error = (60 - 53) / 53 * 100
Percent Error = 7 / 53 * 100
Percent Error = 0.132075 * 100
Percent Error ≈ 13.2%
Therefore, the percent error is approximately 13.2%.
