Question

Lydia received a parking ticket because she parked 10 feet from a fire hydrant. She had estimated her distance from the fire hydrant as being 16 feet. What was her percent error?

Answer 1

she was really 10 feet
she thought 16 feet

she was 6 feet off
her error then is 6feet/10feet error/real value
.6=60%

Answer 2

% error = | your result - accepted value | x 100 %
accepted value

ABS[ (16 - 10)/ 10 ] x 100 % = 6/10 x 100% = 60% error
