Steve has been training for a 5-mile race. Before the race, he predicts he will finish in 42minutes. He actually finishes the race in 40 minutes. What is the percent error for hisprediction?

Answer 1

Explanation:

Answer 2

To find the percent error

percent error = | (actual - expected)/ actual| * 100 %

The actual is 40 and the expected is 42

percent error = | ( 40 - 42) / 40 | * 100 %

= | -2/40| * 100%

= .05 * 100 %

= 5%
