Respuesta :

Answer:

[tex]25%[/tex]%

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

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

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

Error = [tex]|105-84|=21[/tex] minutes

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