Question

Kate thought she could only run for 12 minutes, but she actually ran for 25 minutes. What is the percent error?

Answer 1

Answer:

$108\frac{1}{3}$ %

Step-by-step explanation:

$\frac{25}{12} :\frac{y}{100}$

12 · y = 25 · 100

12y = 2500

12y ÷ 12 = 2500 ÷ 12

$y=208\frac{1}{3}$

$208\frac{1}{3} - 100 = 108\frac{1}{3}$
