Question
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 find the percent error, we can use the formula:
Percent Error = (Actual Value - Predicted Value) / Predicted Value * 100%
In this case, the predicted value is 60 minutes and the actual value is 53 minutes. Plugging these values into the formula, we get:
Percent Error = (53 - 60) / 60 * 100%
= -7 / 60 * 100%
Now we can calculate the percent error:
Percent Error = -0.1167 * 100%
= -11.67%
Rounding to the nearest tenth, the percent error is approximately -11.7%.
