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.

Answer 1

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%.

Answer 2

is it negative or positive
