Question

I predict it will take 23 minutes to drive to my grandma's house today. It actually takes 24 minutes. What is the percent error? Round to the nearest thousandth.

Answer 1

4.167%

Explanation:

Given: It was predicted that it will take 23 minutes to drive to grandma's house but it actually takes 24 minutes.

To find: percent error

Solution:

Predicted time = 23 minutes

Actual time = 24 minutes

Error is the difference between Approximate and Exact Value. Percentage Error is used to compare an estimate value to an exact value.

Error = 24 - 23 = 1 minute

Percent error = (error/actual time) × 100

= 4.167%
