Question

Jocelyn calculates that see will take 105 minutes to run 7 miles. She runs the distance in 84 minutes. What is Jillian’s percent error? (Round final answer to the nearest tenth)​

Answer 1

Answer:

$25%$%

Step-by-step explanation:

Given: Jocelyn calculates that see will take 105 minutes to run 7 miles. She runs the distance in 84 minutes.

To find: Jillian’s percent error

Solution:

Actual time taken by Jocelyn to run 7 miles = 84 minutes

Approximate time taken by Jocelyn to run 7 miles = 105 minutes

Error = $|105-84|=21$ minutes

Percent error = error/(Actual time taken) × (100) = $\frac{21}{84}(100)=25\%$
